Ham Radio Control Libraries

This manual is for Ham Radio Control Libraries (Hamlib) (version 3.3, 20 August 2018).


Copying and Redistribution

This manual documents Hamlib, a programming library and various supplied programs, which is Free Software. Besides often being distributed at no cost to you, Free in this context means that the copyright holders to Hamlib have agreed to offer their collective work under terms that give you certain rights that allow you to modify and/or redistribute Hamlib under the same terms that you received it from them.

Such licensing is often termed copyleft as a play against the common “all rights reserved” terms of normal copyright. In general, copyleft provides everyone with a license to modify and distribute the modified work or to simply distribute a copyrighted work under certain terms. Hamlib source code is copyrighted by its authors and is licensed by them under two common licenses—the GNU Lesser General Public License LGPL for the “front end” and “back end” library source code files, and the GNU General Public License GPL for the supplied programs source code files. The full text of the LGPL and the GPL can be found in the files COPYING.LIB and COPYING in the root directory of the Hamlib source archive.

As part of the Copyleft nature of the licenses, the authors of Hamlib must forbid you from distributing Hamlib under terms that forbid others from exercising the same rights you received. You must give anyone you distribute Hamlib to the same rights to obtain, modify, and distribute the Hamlib source code that you received nor may you license Hamlib under other terms than those you received. Any recipients of Hamlib must be informed of the rights to the source code that they have received.

Finally, the authors of Hamlib require that it be understood that NO WARRANTY of any kind is offered to anyone receiving the Hamlib source code distribution. Anyone distributing modified versions of Hamlib has the responsibility to inform any recipients that what they have is not the official release of Hamlib by its authors and should be prepared to support the modified version(s). This is to preserve the reputations of the Hamlib authors and the Hamlib Project. While it is not a requirement of the licenses, it is courteous to offer modifications back to the Hamlib authors for possible incorporation into their official release(s).


1 Hamlib in a Nutshell

The Ham Radio Control Libraries, Hamlib for short, is a development effort to provide a consistent interface for programmers wanting to incorporate radio and rotator control in their programs.

Hamlib is not a complete user application, rather, it is a software layer intended to make controlling various radios and other amateur radio station (shack) hardware much easier. Hamlib will allow authors of software such as logging programs, digital communications programs, or those wanting to develop the ultimate radio control software to concentrate on the user interface and the basic function of the program rather than radio control. Hamlib consists of several parts, the programming library, utility programs, and library interfaces to other programming languages.

Most recent amateur radio transceivers allow external control of their functions through a serial interface. Unfortunately, control commands are not always consistent across a manufacturer’s product line and each manufacturer’s product line differs greatly from its competitors.

Hamlib attempts to solve this problem by presenting a "virtual radio" to the programmer by providing an interface to actions such as setting a given Variable Frequency Oscillator’s (VFO) frequency, setting the operating mode, querying the radio of its current status and settings, and giving the application a list of a given radio’s capabilities. Unfortunately, what can be accomplished by Hamlib is limited by the radios themselves and some offer very limited capability.

Other devices, such as antenna rotators, can be placed into the Hamlib control scheme. Other recent developments include network interface servers and a USB interface capability. Language bindings are provided for C, C++, Perl, Python, Lua and TCL (more to come).


1.1 A view from the top of the tower

Hamlib is a front end library providing a C language Application Programming Interface API to programmers wishing to integrate radio or rotator control in their applications. Hamlib presents a virtual radio or virtual rotator that is a consistent interface to an application despite wide differences in radio and rotator interfaces and capabilities.

The front end library uses a number of back end libraries to translate from the front end to the various individual radio and rotator models. A back end library handles conversion of the front end variables to the format needed by the radio or rotator device it controls. The back end libraries are generally grouped by manufacturer and in some cases by a common control protocol.

Since a picture is worth quite a few words, here is a visual representation of Hamlib’s design.

Hamlib also provides an interface library for each of several common scripting languages such as Perl, Python, Lua and TCL. These language bindings are generated through the use of SWIG a parser/generator for multiple language interfaces to a C library. A native generated C++ language interface is also provided.

Besides the C and supplemental APIs, Hamlib also provides a pair of network daemons that provide a text command based API for controlling an attached radio or rotator through a TCP/IP network connection. The daemons then handle the interface to the Hamlib C API.

More than one type of device, radio or rotator, may be controlled at a time, however, there is generally a limit of one device per serial port or other port.


1.2 Hamlib project information

The Hamlib Project was founded by Frank Singleton,VK3FCS/KM5WS in July 2000. Shortly after Stephane Fillod, F8CFE, joined Frank on the Hamlib project and the API and implementation development led to a reasonable level of maturity in a few years. A major milestone was reached when Hamlib 1.2.0 was released in March 2004. The API and Application Binary Interface (ABI) interfaces have remained stable since that time up to the latest release of 3.2 in early 2018.

Development continues through the major version number 3.x and beyond. While some API tweaks are planned, ABI compatibility with the prior 1.2.x releases remains a priority. Other goals include streamlining the build system (done), improving the SWIG generated language bindings (done), improving the overall documentation (this manual, in progress), and other updates as warranted.

The Project is hosted by SourceForge.net at the Hamlib project page. As GitHub has become a very popular project hosting site, Hamlib also has a dedicated GitHub project page. GitHub also hosts the hamlib.org Web site and the Hamlib Wiki.

Development discussion and most user support take place on the hamlib-developer mailing list. While there are SourceForge.net discussion forums, they are rarely used and not as closely read by the developers as the mailing list.

For source code management, the project uses Git, a fast, distributed content tracker. Among its features is that every developer has the complete Hamlib development history available locally. For more information on using Git, see Working with Git.

Note: While a canonical Git repository is hosted as SourceForge, its availability is not essential to continued development, although development work flows would change temporarily. Several developers find the GitHub Web interface easier to use and lately development has centered around GitHub rather than SourceForge.


1.3 Applications using Hamlib

A number of application developers have taken advantage of Hamlib’s capabilities to implement radio and/or rotator control. While not exhaustive, a list is maintained at the Hamlib Wiki, Applications/Screenshots. Developers are encouraged to request their applications be added to the gallery by way of the hamlib-developer mailing list.


1.4 Using Hamlib with your program

As with other Free Software projects, Hamlib relies heavily on copyleft licensing to encourage development contributions and provide an open atmosphere for development. Hamlib’s source code is released under two licenses, the Lesser General Public License (LGPL) for the library portion, and the General Public License (GPL) for the utility programs.

The LGPL allows the library to be used (linked) by programs regardless of their individual license. However, any contributions to the library source remain under copyleft which means that the library source code may not be used in violation of the terms of the LGPL.

The utility program source files are released under the GPL. Any direct use of these sources must be in a form that complies with the terms of the GPL. Concepts learned by studying these sources for the purpose of understanding the Hamlib API is not covered nor prohibited by the GPL, however, directly copying GPL sources into any work that is incompatible with the terms of the GPL is prohibited.

See Copying and Redistribution.


1.5 Radios with a clone capability

Hamlib’s focus is on controlling rigs that employ a port and command protocol for setting frequency, mode, VFO, PTT, etc. Most VHF/UHF transceivers do not employ such control capability but do provide for cloning the memory contents from radio to another of the same model. A related project, CHIRP, aims to support radios with such a clone capability. Please contact the CHIRP project for support of such radios.


1.6 Pronouncing Hamlib

English speakers seem to have two alternate pronunciations for our project:

Then again, we have people who say Linux "L-eye-nux" and those who say "L-in-nux"...

If you’re French, the above does not apply! :-)


2 Getting started

There are several ways to obtain a working installation of Hamlib. The following sections discuss installing from a package manager, building from source, and installing Hamlib project supplied binaries on Microsoft Windows®.


2.1 Installing binary packages on Linux and BSD

The easiest way to install a released version of Hamlib on a Linux based distribution or a BSD variant is through the provided package manager. While package managers vary according to the distribution (it’s easy to lump BSD variants in this group too) their end goal is to provide ready to use software packages. Since such a wide variety of package managers exist, it is best to recommend that the documentation for your chosen distribution be your guide.


2.2 A variety of Hamlib sources

Distribution packages are most often official Hamlib releases and in some cases could be quite old and lacking support for newer radios or rotators. In some cases support is improved in existing radio or rotator back ends and bugs are fixed in newer releases. Often times to get the improved support/bug fixes, building from source will be required. Relax, it’s not hard. :-)

Source code is available as official releases, testing snapshots, daily development snapshots, and the bleeding edge of development directly from the Git repository. As a rule, even the bleeding edge tarballs should configure and compile without error even though certain implementation work may be in progress and may be incomplete or have errors.


2.2.1 Getting released source

Official Hamlib source releases, commonly called tarballs can be found on the SourceForge.net Hamlib files Web page. As a convenience, release archives are also mirrored at the GitHub Hamlib releases page. The most recent release is listed first.


2.2.2 Getting source snapshots

Testing release candidates (RCs) are posted during the period (often a few weeks) before a planned release. Beginning with the 3.2 release, RCs are hosted by the GitHub release archive. RCs are identifed by having a ~rc suffix.

Daily snapshots of the development repository are available via the World Wide Web from Hamlib Git daily snapshots. These are not official releases but are provided for testing new features and bug fixes.

The daily development snapshot is made and posted each day by around 1030 UTC. Daily snapshots should compile but sometimes a bug creeps in that prevents compilation. If that should happen, please report it to the hamlib-developer mailing list.


2.2.3 Git repository

The source repository can be cloned which copies the repository to your computer including its entire history, branches, and release tag information. In other words, once the git clone command is finished a complete copy of the Hamlib development will be on your computer. You can do quite a lot with this as nothing is hidden from view since the entire history of Hamlib is right there all the way from the very first commit to the present. None of the meta-data is hidden away on some central server.

To clone the repository use the following command:

git clone git://git.code.sf.net/p/hamlib/code hamlib

or:

git clone https://github.com/Hamlib/Hamlib.git

Odds are that you will want to run the above command in a sub directory of your home directory. The hamlib directory will be created by Git and the master branch will be checked out for you as the working copy. The master branch is one of several branches used in Hamlib development. It is the main branch of new features and bug fixes. The working copy will be the latest revision of every file at the time of the clone. Later updates from the developers will require using another Git command to update your local repository.

See Working with Git.


2.3 Building from source

Building from source will be required for various reasons. Perhaps only an older release is provided by your distribution, or you would like to test recent changes to Hamlib—either a specific back end or API changes—and offer a report to the developers, or you’d like to take part in development and offer your contribution to the project, or you’d just like to learn how to build a relatively comprehensive package from source. Any is a good reason to build from the source code archive.

Before going further, this manual assumes familiarity with working from the command prompt in a Linux/BSD/Unix like system’s shell environment, either in a virtual console (a text only screen with no graphics) or in a terminal in a desktop environment (xterm, rxvt, konsole, gnome-terminal, xfce4-terminal, terminal, etc.). If this is new to you, take some time and read up on using the shell. A good tutorial can be found at LinuxCommand.org which also offers an in-depth book that can be purchased or downloaded for no cost (the Hamlib project is not associated with nor has any interest in the sale of this book, it just looks like a very good effort on the part of its author).

Let’s get started.


2.3.1 Compiling source tarballs

Before proceeding, it is essential to read the information in the files, README, INSTALL, and README.betatester supplied in the Hamlib top-level directory which will be named something like hamlib-3.3~git where the latter part is the release version. In this case the ‘3.3~git’ indicates this is a development snapshot of the Git master branch. These files provide detailed information for compiling Hamlib and will vary some from release to release.

Compiling from a source tarball whether it is an official release or a testing or daily development snapshot follows the same set of commands, known as the three step which are each run from the top-level directory:

./configure
make
sudo make install

2.3.1.1 configure

The ./configure command examines your system and checks it for any packages that are required or good to have options for compiling Hamlib. The leading ./ tells the shell to only run the configure command found in the current directory. It is always possible that a configure command could be lurking elsewhere and we don’t want to run that!

Run:

./configure

from the top-level directory.

Note: Some distributions are configured so commands can only be run from directories listed in the PATH environment variable. The ./ is necessary or the configure command will not be run as the current directory (defined as .) is not in the PATH. This is considered a default security feature so that only programs provided by the distribution are run. PATH can be modified for your own session, but that is a topic for the LinuxCommand.org reference above.

Of course, things are usually complicated a bit by options and Hamlib is no exception. The good news is that the defaults, i.e., no options, work well in most situations. Options are needed to enable the compilation of certain portions of Hamlib such as the language bindings. Optional features usually require that more development tools are installed. The INSTALL, and README.betatester files in the Hamlib top-level directory will have details on the options available for that release.

A useful option is ‘--prefix’ which tells configure where in the file system hierarchy Hamlib should be installed. If it is not given, Hamlib will be installed in the /usr/local file system hierarchy. Perhaps you want to install to your home directory instead:

./configure --prefix=$HOME/local

Note: For practice you may wish to start out using the ‘--prefix=$HOME/local’ option to install the Hamlib files into your home directory and avoid overwriting any version of Hamlib installed into the system directories. The code examples in the remainder of this manual will assume Hamlib has been installed to ‘$HOME/local’.

All of the files will be installed in the local directory of your home directory. local will be created if it does not exist during installation as will several other directories in it. Installing in your home directory means that root, or superuser (administrator) privileges are not required when running make install. On the other hand, some extra work will need to be done so other programs can use the library.

Another useful option is ‘--help’ which will give a few screens full of options for configure. If in a desktop environment the scroll bar can be used to scroll back up through the output. In either a terminal or a virtual console Linux supports the Shift-PageUp key combination to scroll back up. Converesely Shift-PageDown can be used to scroll down toward the end of the output and the shell prompt (Shift-UpArrow/Shift-DownArrow may also work to scroll one line at a time).

After a fair amount of time, depending on your computer, and a lot of screen output, configure will finish its job. So long as the few lines previous to the shell prompt don’t say “error” or some such failure message Hamlib is ready to be compiled. If there is an error and all of the required packages listed in README.betatester have been installed, please ask for help on the hamlib-developer mailing list.


2.3.1.2 make

The make command is responsible for running the compiler which reads the source files and from the instructions it finds in them writes object files which are the binary instructions the CPU of a computer can execute. make then calls the linker which puts the object files together in the correct order to create the Hamlib library files and its executable programs.

Run:

make

from the top-level directory.

Any error that causes make to stop early is cause for a question to the hamlib-developer mailing list.

In general make will take longer than configure to complete its run. As it is a system command and therefore found in the PATH, prefixing make with ./ will cause a ‘command not found’ error from the shell.


2.3.1.3 make install

Assuming that you have not set the installation prefix to your home directory, root (administrator) privileges will be required to install Hamlib to the system directories. Two popular methods exist for gaining root privileges, su and sudo. sudo is probably the most popular these days, particularly when using the Ubuntu family of distributions.

Run:

sudo make install

as root from the top-level directory.

Running make install will call the installer to put all of the newly compiled files and other files (such as this document) in predetermined places set by the ‘--prefix’ option to configure in the directory hierarchy (yes, this is by design and make is not just flinging files any old place!).

A lot of screen output will be generated. Any errors will probably be rather early in the process and will likely be related to your username not having write permissions in the system directory structure.


2.3.1.4 ldconfig

Once the installation is complete one more step is required if Hamlib has never been installed from a local build before. The ldconfig command tells the system library loader where to find the newly installed Hamlib libraries. It too will need to be run with root privileges:

Run:

sudo ldconfig

as root from any directory.

Note: Subsequent installations of Hamlib will not need to have ldconfig run after each installation if a newer major version of Hamlib was not installed, i.e. when recompiling the same version during development.

On some distributions a bit of configuration will be needed before ldconfig will add locally compiled software to its database. Please consult your distribution’s documentation.


2.3.2 Bootstrapping from a git clone

Choosing to build from from a git clone requires a few more development tools (notice a theme here?) as detailed in README.developer. The most critical will be the GNU Autotools (autoconf, automake, libtool, and more) from which the build system consisting of configure, the various Makefile.ins throughout the directory structure, and the final Makefiles are generated.

In the top-level directory is the bootstrap script from which the build system is bootsrapped—the process of generating the Hamlib build system from configure.ac and the various Makefile.ams. At its completion the configure script will be present to configure the build system.

Next configure is run with any needed build options (configure --help is useful) to enable certain features or provide paths for locating needed build dependencies, etc. Environment variables intended for the preprocessor and/or compiler may also be set on the configure command line.

After the configuration is complete, the build may proceed with the make step as for the source tarballs above. Or configure --help may be run, and configure run again with specific options in which case the Makefiles will be regenerated and the build can proceed with the new configuration.

See configure.


2.3.3 Other make targets

Besides make install, other targets exist when running make. Running make clean from the top-level directory removes all of the generated object and executable files generated by running make freeing up considerable disk space.

Note: During development of individual source files, it is not necessary to run make clean each time before make. Simply run make and only the modified file(s) and any objects that depend on them will be recompiled. This speeds up development time considerably.

To remove even the generated Makefiles, run make distclean from the top-level directory. After this target is run, configure will need to be run again to regenerate the Makefiles. This command may not be as useful as the Makefiles do not take up much space, however it can be useful for rebuilding the Makefiles when modifying a Makefile.am or confgure.ac during build system development.


2.3.4 Parallel build trees

One feature of the GNU build system used by Hamlib is that the object files can be kept in a directory structure separate from the source files. While this has no effect on the make targets described above, it does help the developer find files in the source tree! One such way of using parallel builds is described in README.developer.

Parallel builds can be very useful as one build directory can be configured for a release and another build directory can be configured for debugging with different options passed to configure from each directory. The generated Makefiles are unique to each build directory and will not interfere with each other.


2.3.5 Adding debugging symbols

When additional debugging symbols are needed with, for example, the GNU Debugger, gdb, the needed compiler and linker options are passed as environment variables.

Run:

../hamlib/configure CFLAGS="-ggdb3 -O0" CXXFLAGS="-ggdb3 -O0"

from a sibling build directory intended for a debugging build.

The ‘-ggdb3’ option tells the C compiler, this case the GNU C Compiler, gcc, to add special symbols useful for GDB, the GNU debugger. The ‘-O0’ option tells gcc to turn off all optimizations which will make it easier to follow some variables that might otherwise be optimized away. ‘CFLAGS’ and ‘CXXFLAGS’ may be set independently for each compiler.

Note: There are a number compiler options available for controlling debugging symbols and setting optimization levels. Please consult the compiler’s manual for all the details.


2.3.6 Compiling for Microsoft Windows

Currently compiling is done on a Debian 8 (Jessie) virtual machine using MinGW. README.build-win32 in the scripts directory has details on how this is accomplished.

Work is ongoing to correct build issues in the Cygwin environment running on MS Windows.


2.4 Pre-compiled binaries for Microsoft Windows

Pre-compiled binaries for Microsoft Windows 32 and 64 bit architectures (Windows NT and newer) are available for both official releases and daily development snapshots. Official releases are available through the SourceForge.net file download service. As an alternative, official releases are also available though the Hamlib archive at GitHub. Daily development snapshots are available from http://n0nb.users.sourceforge.net/.

Beginning with the Hamlib 1.2.15.3 release a self-extracting installer is available. Among its features are selecting which portions of Hamlib are installed. The PATH environment variable will need to be set manually per the included README.w32-bin or README.w64-bin file.

Daily development snapshots feature both a .ZIP archive and the self extracting installer.

Bug reports and questions about these archives should be sent to the hamlib-developer mailing list.


3 Utility programs reference

Included with the Hamlib distribution are several utility programs. Besides providing a way for developers to test new code and bug fixes, the programs also offer a reference implementation for interfacing to the Hamlib library functions both through the C API (Application Programming Interface) and offering a network accessible API.

This chapter focuses on the two test programs, rigctl for testing radio back ends and rotctl for testing rotator back ends and the two network daemons, rigctld and rotcltd for radio and rotator access via network sockets. Also included are three demonstation utilities, rigmem, rigsmtr, and rigswr which provide functional examples of how Hamlib may be used to accomplish various tasks.


3.1 rigctl

rigctl is the most frequently used Hamlib utility. As the other ctl utilities share many of the same characteristics, much of the introductory information presented in this section is applicable to the other utility programs.


3.1.1 Introduction to rigctl

Most likely the first of the Hamlib utility programs that is used is rigctl. rigctl is a character based interactive program and a command line program able to set or query a radio’s value with a single command. rigctl is invoked from a shell command prompt with various options and additional commands.

In its most simple use as a command line program, rigctl is used to set frequency and mode by typing commands after any rigctl options:

rigctl F 14205000
rigctl M USB 2400

and then query those values:

rigctl f
rigctl m

Entering interactive mode is a simple matter of not placing any commands after any rigctl options:

rigctl

Entering interactive mode allows successive commands to be entered without exiting rigctl. Recent additions to rigctl allow command editing and history recall through use of the Readline library.

Interactive mode is indicated by the spartan prompt:

Rig command:

Commands are given at the prompt and follow the general rule that upper case letters set a value and lower case letters query a value:

Rig command: M
Mode: USB
Passband: 2500

Rig command: m
Mode: USB
Passband: 2500

Rig command:

An additional prompt is printed when more information is required by the command. For M above, rigctl prompted for the “Mode” and “Passband” values. For m above, rigctl returned the “Mode” and “Passband” values without further prompts. The command prompt is returned after each command invocation.

The above examples invoked rigctl without specifying a radio model. This is a feature where the Hamlib internal radio dummy is used instead. The dummy radio provides a way to test Hamlib functions with out the need for actual radio hardware. However, to develop back end capability for a given radio, having the actual radio connected to the computer is necessary for debugging.

For example, to quickly set frequency on an Elecraft K3:

rigctl -m 229 -r /dev/rig F 3900000

and to query the frequency and then mode:

rigctl -m 229 -r /dev/rig f
3900000

rigctl -m 229 -r /dev/rig m
LSB
2000

The returned values do not have the prompt strings associated with interactive mode as shown above.

The -m option takes a numeric value that corresponds to a given radio back end model. The -r option takes the path to the port device on POSIX and the device name on Microsoft Windows.

Note: A complete list of supported radio models may be seen by use of the -l option:

rigctl -l
 Rig #  Mfg              Model         Version    Status

  2901  ADAT www.adat.ch ADT-200A      1.36       Beta

The list is long so use SHIFT-PageUp/ SHIFT-PageDown on Linux, ScrollLock then PageUp/PageDown on Free BSD, or use the scrollbar to the virtual terminal window (cmd window on Microsoft Windows) or the output can be piped to ’more’ or ’less’, e.g. ’rigctl -l | more’ to scroll back up the list. The list is sorted numerically by model number since Hamlib 1.2.15.1. Model numbers of a manufacturer/protocol family are grouped together.


3.1.2 rigctl reference

The complete reference for rigctl can be found in the rigctl(1) Unix manual page.


3.2 rotctl

Identical in function to rigctl, rotctl provides a means for testing Hamlib functions useful for rotator control and QTH (Maidenhead gridsquare system, see Maidenhead Locator System) locator computations. As rotators have a much narrower scope than radios, there are fewer command line options and commands for rotctl.


3.2.1 Introduction to rotctl

rotctl is a character based interactive program and a command line program able to set or query a rotator’s value with a single command. rotctl is invoked from a shell command prompt with various options and additional commands.

In its most simple use as a command line program, rotctl is used to set frequency and mode by typing commands after any rotctl options:

rotctl P 145.0 23.0
rotctl M 8 25

and then query those values:

rotctl p

Entering interactive mode is a simple matter of not placing any commands after any rotctl options:

rotctl

Entering interactive mode allows successive commands to be entered without exiting rotctl. Interactive mode allows for command editing and history recall through the use of the Readline library.

Interactive mode is indicated by the spartan prompt:

Rotator command:

Commands are given at the prompt:

Rotator command: M
Direction: 16
Speed: 60

Rotator command: p
Azimuth: 11.352000
Elevation: 0.000000

Rotator command: p
Azimuth: 27.594000
Elevation: 0.000000

Rotator command:

An additional prompt is printed when more information is required by the command. For M above, rotctl prompted for the “Direction” and “Speed” values. For p above, rotctl returned the “Azimuth” and “Elevation” values without further prompts. The command prompt is returned after each command invocation.

The above examples invoked rotctl without specifying a rotator model. This is a feature where the Hamlib internal rotator dummy is used instead. The dummy rotator provides a way to test Hamlib functions with out the need for actual rotator hardware. However, to develop back end capability for a given rotator, having the actual controller connected to the computer is necessary for debugging.

For example, to quickly set position for RotorEZ:

rotctl -m 401 -r /dev/rotor P 100.0 0.0

and to query the position:

rotctl -m 401 -r /dev/rotor p
100.000000
0.000000

The returned values do not have the prompt strings associated with interactive mode as shown above.

The -m option takes a numeric value that corresponds to a given rotator back end model. The -r option takes the path to the port device on POSIX or the device name on MS Windows.

Note: A complete list of supported radio models may be seen by use of the -l option:

The list is long so use SHIFT-PageUp/ SHIFT-PageDown on Linux, ScrollLock then PageUp/PageDown on Free BSD, or use the scrollbar to the virtual terminal window (cmd window on MS Windows) or the output can be piped to ’more’ or ’less’, e.g. ’rotctl -l | more’ to scroll back up the list. The list is sorted numerically by model number since Hamlib 1.2.15.1. Model numbers of a manufacturer/protocol family are grouped together.


3.2.2 rotctl reference

The complete reference for rotctl can be found in the rotctl(1) Unix manual page.


3.3 rigctld

The rigctld program is a network server that accepts the familiar commands of rigctl and provides the response data over a TCP/IP network socket to an application. In this manner an application can access a rigctld instance from nearly anywhere (caveat, no security is currently provided by rigctld). Applications using rigctld do not link directly to Hamlib nor use its C API.


3.3.1 Introduction to rigctld

rigctld communicates to a client through a TCP network socket using text commands shared with rigctl. The protocol is simple; commands are sent to rigctld on one line and rigctld responds to “get” commands with the requested values, one per line, when successful, otherwise, it responds with one line ‘RPRT x’, where ‘x’ is a negative number indicating the Hamlib error code. Commands that do not return values respond with the line ‘RPRT x’, where ‘x’ is zero when successful, otherwise a negative number indicating the Hamlib error code. Each line is terminated with a newline \n character. This protocol is primarily for use by the NET rigctl (radio model 2) backend.

A separate Extended Response protocol extends the above behavior by echoing the received command string as a header, any returned values as a key: value pair, and the ‘RPRT x’ string as the end of response marker which includes the Hamlib success or failure value. Consider using this protocol for clients that will interact with rigctld directly through a TCP network socket.

Multiple radios can be controlled on different TCP ports by use of multiple rigctld processes each listening on a unique TCP port. It is hoped that rigctld will be especially useful for client authors using languages such as Perl, Python, PHP, Ruby, TCL, and others.

3.4 rotctld

The rotctld program is a network server that accepts the familiar commands of rotctl and provides the response data over a TCP/IP network socket to an application. In this manner an application can access a rotctld instance from nearly anywhere (caveat, no security is currently provided by rotctld). Applications using rotctld do not link directly to Hamlib nor use its C API.


3.4.1 Introduction to rotctld

rotctld communicates to a client through a TCP network socket using text commands shared with rotctl. The protocol is simple, commands are sent to rotctld on one line and rotctld responds to “get” commands with the requested values, one per line, when successful, otherwise, it responds with one line ‘RPRT x’, where ‘x’ is a negative number indicating the Hamlib error code. Commands that do not return values respond with the line ‘RPRT x’, where ‘x’ is zero when successful, otherwise a negative number indicating the Hamlib error code.

Consider using this protocol for clients that will interact with rotctld directly through a TCP network socket.

Multiple rotators can be controlled on different TCP ports by use of multiple rotctld processes each listening on a unique TCP port. It is hoped that rotctld will be especially useful for client authors using languages such as Perl, Python, PHP, Ruby, TCL, and others.


3.4.2 rotctld reference

3.5 rigmem

rigmem may be used to backup and restore memory of radio transceivers and receivers.


3.5.1 Introduction to rigmem

Backup and restore memory of radio transceivers and receivers. rigmem accepts ‘command’s from the command line only.


3.5.2 rigmem reference

The complete reference for rigmem can be found in the rigmem(1) Unix manual page.


3.6 rigsmtr

rigsmtr uses Hamlib to control a radio to measure S-Meter value versus antenna azimuth.


3.6.1 Introduction to rigsmtr

rigsmtr rotates the antenna from minimum azimuth to maximum azimuth. Every second, or time_step if specified in seconds, it retrieves the signal strength. Azimuth in degrees and the corresponding S-Meter level in dB relative to S9 are then printed on stdout.

To work correctly, rigsmtr needs a radio that could measure S-Meter and a Hamlib backend that is able to retrieve it, connected to a Hamlib supported rotator.


3.6.2 rigsmtr reference

The complete reference for rigsmtr can be found in the rigsmtr(1) Unix manual page.


3.7 rigswr

rigswr may be used to measure VSWR vs frequency.


3.7.1 Introduction to rigswr

rigswr uses Hamlib to control a radio to measure VSWR (Voltage Standing Wave Ratio) over a frequency range. It scans frequencies from start_freq to stop_freq with an optional increment of freq_step (default step is 100 kHz). All values must be entered as an integer in Hertz (cycles per second).

Note: rigswr assumes that start_freq is less than or equal to stop_freq. If it is greater, rigswr will exit without doing anything.

For each frequency, rigswr transmits at 25% of total POWER during 0.5 second in CW mode and reads VSWR.

Frequency and the corresponding VSWR are then printed on stdout.

To work correctly, rigswr needs a radio that can measure VSWR and a Hamlib backend that supports reading VSWR from the radio.


3.7.2 rigswr reference

The complete reference for rigswr can be found in the rigswr(1) Unix manual page.


Appendix A GNU Free Documentation License

Version 1.3, 3 November 2008
Copyright © 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
http://fsf.org/

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
  1. PREAMBLE

    The purpose of this License is to make a manual, textbook, or other functional and useful document free in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others.

    This License is a kind of “copyleft”, which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software.

    We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference.

  2. APPLICABILITY AND DEFINITIONS

    This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The “Document”, below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as “you”. You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law.

    A “Modified Version” of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language.

    A “Secondary Section” is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document’s overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.

    The “Invariant Sections” are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none.

    The “Cover Texts” are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words.

    A “Transparent” copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not “Transparent” is called “Opaque”.

    Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only.

    The “Title Page” means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, “Title Page” means the text near the most prominent appearance of the work’s title, preceding the beginning of the body of the text.

    The “publisher” means any person or entity that distributes copies of the Document to the public.

    A section “Entitled XYZ” means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as “Acknowledgements”, “Dedications”, “Endorsements”, or “History”.) To “Preserve the Title” of such a section when you modify the Document means that it remains a section “Entitled XYZ” according to this definition.

    The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License.

  3. VERBATIM COPYING

    You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.

    You may also lend copies, under the same conditions stated above, and you may publicly display copies.

  4. COPYING IN QUANTITY

    If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document’s license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.

    If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.

    If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.

    It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.

  5. MODIFICATIONS

    You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:

    1. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission.
    2. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement.
    3. State on the Title page the name of the publisher of the Modified Version, as the publisher.
    4. Preserve all the copyright notices of the Document.
    5. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices.
    6. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below.
    7. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document’s license notice.
    8. Include an unaltered copy of this License.
    9. Preserve the section Entitled “History”, Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled “History” in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence.
    10. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the “History” section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission.
    11. For any section Entitled “Acknowledgements” or “Dedications”, Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein.
    12. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles.
    13. Delete any section Entitled “Endorsements”. Such a section may not be included in the Modified Version.
    14. Do not retitle any existing section to be Entitled “Endorsements” or to conflict in title with any Invariant Section.
    15. Preserve any Warranty Disclaimers.

    If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version’s license notice. These titles must be distinct from any other section titles.

    You may add a section Entitled “Endorsements”, provided it contains nothing but endorsements of your Modified Version by various parties—for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.

    You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.

    The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version.

  6. COMBINING DOCUMENTS

    You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers.

    The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work.

    In the combination, you must combine any sections Entitled “History” in the various original documents, forming one section Entitled “History”; likewise combine any sections Entitled “Acknowledgements”, and any sections Entitled “Dedications”. You must delete all sections Entitled “Endorsements.”

  7. COLLECTIONS OF DOCUMENTS

    You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.

    You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document.

  8. AGGREGATION WITH INDEPENDENT WORKS

    A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an “aggregate” if the copyright resulting from the compilation is not used to limit the legal rights of the compilation’s users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document.

    If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document’s Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate.

  9. TRANSLATION

    Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail.

    If a section in the Document is Entitled “Acknowledgements”, “Dedications”, or “History”, the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title.

  10. TERMINATION

    You may not copy, modify, sublicense, or distribute the Document except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, or distribute it is void, and will automatically terminate your rights under this License.

    However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.

    Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.

    Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, receipt of a copy of some or all of the same material does not give you any rights to use it.

  11. FUTURE REVISIONS OF THIS LICENSE

    The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/.

    Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License “or any later version” applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. If the Document specifies that a proxy can decide which future versions of this License can be used, that proxy’s public statement of acceptance of a version permanently authorizes you to choose that version for the Document.

  12. RELICENSING

    “Massive Multiauthor Collaboration Site” (or “MMC Site”) means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A “Massive Multiauthor Collaboration” (or “MMC”) contained in the site means any set of copyrightable works thus published on the MMC site.

    “CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0 license published by Creative Commons Corporation, a not-for-profit corporation with a principal place of business in San Francisco, California, as well as future copyleft versions of that license published by that same organization.

    “Incorporate” means to publish or republish a Document, in whole or in part, as part of another Document.

    An MMC is “eligible for relicensing” if it is licensed under this License, and if all works that were first published under this License somewhere other than this MMC, and subsequently incorporated in whole or in part into the MMC, (1) had no cover texts or invariant sections, and (2) were thus incorporated prior to November 1, 2008.

    The operator of an MMC Site may republish an MMC contained in the site under CC-BY-SA on the same site at any time before August 1, 2009, provided the MMC is eligible for relicensing.

ADDENDUM: How to use this License for your documents

To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page:

  Copyright (C)  year  your name.
  Permission is granted to copy, distribute and/or modify this document
  under the terms of the GNU Free Documentation License, Version 1.3
  or any later version published by the Free Software Foundation;
  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
  Texts.  A copy of the license is included in the section entitled ``GNU
  Free Documentation License''.

If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the “with…Texts.” line with this:

    with the Invariant Sections being list their titles, with
    the Front-Cover Texts being list, and with the Back-Cover Texts
    being list.

If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation.

If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.


Appendix B Working with Git

Git offers a myriad of commands and options. Fortunately, only a few are needed for Hamlib development.
