RIGCTLD(1)

NAME
rigctld - TCP radio control daemon

SYNOPSIS
rigctld [-hlLouV] [-m id] [-r device] [-p device] [-d device] [-P type] [-D type] [-s baud] [-c id] [-T IPADDR] [-t number] [-C parm=val] [-X seconds] [-v[-Z]]

DESCRIPTION
The rigctld program is a radio control daemon that handles client requests via TCP sockets. This allows multiple user programs to share one radio (this needs more development). Multiple radios can be controlled on different TCP ports by use of multiple rigctld processes. Note that multiple processes/ports are also necessary if some clients use extended responses and/or vfo mode. So up to 4 processes/ports may be needed for each combination of extended response/vfo mode. The syntax of the commands are the same as rigctl(1). It is hoped that rigctld will be especially useful for client authors using languages such as Perl, Python, PHP, and others.

rigctld communicates to a client through a TCP 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 error code. Commands that do not return values respond with the line “RPRT x”, where ‘x’ is ‘0’ when successful, otherwise is a regative number indicating the 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. See the PROTOCOL section for details. Consider using this protocol for clients that will interact with rigctld directly through a TCP socket.

Keep in mind that Hamlib is BETA level software. While a lot of backend libraries lack complete rotator support, the basic functions are usually well supported.

Please report bugs and provide feedback at the e-mail address given in the BUGS section below. Patches and code enhancements sent to the same address are welcome.

OPTIONS
This program follows the usual GNU command line syntax. Short options that take an argument may have the value follow immediately or be separated by a space. Long options starting with two dashes (‘-’) require an ‘=’ between the option and any argument.

Here is a summary of the supported options:

-m, --model=id
    Select radio model number. Defaults to dummy device.

    See model list (use “rigctl -l”).

    Note: rigctl (or third party software using the C API) will use radio model 2 for NET rigctl (this model number is not used for rigctld even though it shows in the model list).

-r, --rig-file=device
    Use device as the file name of the port connected to the radio.

    Often a serial port, but could be a USB to serial adapter. Typically /dev/ttyS0, /dev/ttyS1, /dev/ttyUSB0, etc. on Linux, COM1, COM2, etc. on MS Windows. The BSD flavors and Mac OS/X have their own designations. See your system's documentation.

    Can be a network address:port, e.g. 127.0.0.1:12345

    The special string “uh-rig” may be given to enable micro-ham device support.

-p, --ptt-file=device
    Use device as the file name of the Push-To-Talk device using a device file as described above.

-d, --dcd-file=device
    Use device as the file name of the Data Carrier Detect device using a device file as described above.

-P, --ptt-type=type
    Use type of Push-To-Talk device.

    Supported types are ‘RIG’ (CAT command), ‘DTR’, ‘RTS’, ‘PARALLEL’, ‘NONE’, overriding PTT type defined in the rig's backend.

    Some side effects of this command are that when type is set to DTR, read PTT state comes from the Hamlib frontend, not read from the radio. When set to NONE, PTT state cannot be read or set even if rig backend supports reading/setting PTT status from the rig.

-D, --dcd-type=type
    Use type of Data Carrier Detect device.

    Supported types are ‘RIG’ (CAT command), ‘DSR’, ‘CTS’, ‘CD’, ‘PARALLEL’, ‘NONE’.

-s, --serial-speed=baud
    Set serial speed to baud rate.

    Uses maximum serial speed from radio backend capabilities (set by -m above) as the default.

-c, --civaddr=id
    Use id as the CI-V address to communicate with the rig.

    Only useful for Icom and some Ten-Tec rigs.

    Note: The id is in decimal notation, unless prefixed by 0x, in which case it is hexadecimal.

-S, --separator=char
    Use char as separator instead of line feed

    The default is Recommend using $ or @ as they work on both Unix and Windows

-T, --listen-addr=IPADDR
    Use IPADDR as the listening IP address.

    The default is ANY (0.0.0.0).

    rigctld can be run and connected to like this:

        rigctld
        rigctl -m 2
        rigctl -m 2 -r 127.0.0.1
        rigctl -m 2 -r localhost
        rigctl -m 2 -r 192.168.1.1 (local IP address)
        rigctl -m 2 -r ::1 (on Linux rigctld doesn't listen on IPV6 by default)

    rigctld -T 127.0.0.1
    rigctl -m 2
    rigctl -m 2 -r 127.0.0.1
Exceptions:
    rigctl -m 2 -r localhost (only works if localhost is IPV4 address)

        rigctld -T localhost (will set up on IPV4 or IPV6 based on localhost)
        rigctl -m 2
        rigctl -m 2 -r localhost
        rigctl -m 2 ip6-localhost
    Exceptions:
        rigctl -m 2 -r 127.0.0.1 (only works if localhost is IPV4 address)
        rigctl -m 2 -r ::1 (only works localhost is IPV6 address)

    On Linux only where ip6-localhost is fe00::0:
        rigctld -T ip6-localhost
        rigctl -m 2 -r ip6-localhost

-t, --port=number
    Use number as the TCP listening port.

    The default is 4532.

    Note: As rotctld's default port is 4533, it is advisable to use even numbered ports for rigctld, e.g. 4532, 4534, 4536, etc.

-L, --show-conf
    List all config parameters for the radio defined with -m above.

-C, --set-conf=parm=val[,parm=val]
    Set configuration parameter(s). Some common ones are:
        write_delay:Delay in ms between each byte sent out
        post_write_delay:Delay in ms between each command sent out
        timeout:Timeout in ms
        retry:Max number of retry
        ptt_type:Push-To-Talk interface type override
        ptt_pathname:Path name to the device file of the Push-To-Talk
        ptt_bitnum:Push-To-Talk GPIO bit number
        dcd_type:Data Carrier Detect (or squelch) interface type override
        dcd_pathname:Path name to the device file of the Data Carrier Detect (or squelch)
        lo_freq:Frequency to add to the VFO frequency for use with a transverter
        auto_power_on:True enables compatible rigs to be powered up on open
        auto_power_off:True enables compatible rigs to be powered down on close
        auto_disable_screensaver:True enables compatible rigs to have their screen saver disabled on open
        disable_yaesu_bandselect:True disables the automatic band select on band change for Yaesu rigs
        ptt_share:True enables ptt port to be shared with other apps
        twiddle_timeout:For satellite ops when VFOB is twiddled will pause VFOB commands until timeout
        twiddle_rit:Suppress get_freq on VFOB for RIT tuning satellites
        async:True enables asynchronous data transfer for backends that support it. This allows use of transceive and spectrum data.
        tuner_control_pathname:Path name to a script/program to control a tuner with 1 argument of 0/1 for Tuner Off/On

    Use the -L option above for a list of configuration parameters for a given model number.

-u, --dump-caps
    Dump capabilities for the radio defined with -m above and exit.

-l, --list
    List all model numbers defined in Hamlib and exit.

    The list is sorted by model number.

    Note: In Linux the list can be scrolled back using Shift-PageUp/Shift-PageDown, or using the scrollbars of a virtual terminal in X or the cmd window in Windows. The output can be piped to more(1) or less(1), e.g. “rigctl -l | more”.

-o, --vfo
    Enable vfo mode.

    An extra VFO argument will be required in front of each appropriate command (except set_vfo). Otherwise, ‘currVFO’ is used when this option is not set and an extra VFO argument is not used.

    See chk_vfo below.

-v, --verbose
    Set verbose mode, cumulative (see DIAGNOSTICS below).

-W, --twiddle_timeout=seconds
    Enables timeout when VFO twiddling is detected. Some functions will be ignored.

    Should only be needed when controlling software should be "paused" so you can move the VFO. Continuous movement extends the timeout.

-x, --uplink=option
    1=Sub, 2=Main

    For GPredict use to ignore get_freq for Sub or Main uplink VFO.

    Should allow downlink VFO movement without confusing GPredict or the uplink

-Z, --debug-time-stamps
    Enable time stamps for the debug messages.

    Use only in combination with the -v option as it generates no output on its own.

-A, --password
    Sets password on rigctld which requires hamlib to use rig_set_password and rigctl to use \password to access rigctld. A 32-char shared secret will be displayed to be used on the client side.

-R, --rigctld_idle
    Will make rigctld close the rig when no clients are connected. Normally remains connected to speed up connects.

-h, --help
    Show a summary of these options and exit.

-V, --version
    Show version of rigctl and exit.

Note: Some options may not be implemented by a given backend and will return an error. This is most likely to occur with the --set-conf and --show-conf options.

Please note that the backend for the radio to be controlled, or the radio itself may not support some commands. In that case, the operation will fail with a Hamlib error code.

COMMANDS
Commands can be sent over the TCP socket either as a single char, or as a long command name plus the value(s) space separated on one ‘\n’ terminated line. See PROTOCOL.

Since most of the Hamlib operations have a set and a get method, a single pper case letter will be used for set methods whereas the corresponding single lower case letter refers to the get method. Each operation also has a long name; prepend a backslash, ‘\’, to send a long command name all in lower case.

Example (Perl): “print $socket "\\dump_caps\n";” to see what the radio's backend can do (Note: In Perl and many other languages a ‘\’ will need to be escaped with a preceding ‘\’ so that even though two backslash characters appear in the code, only one will be passed to rigctld. This is a possible bug, beware!).

Note: The backend for the radio to be controlled, or the radio itself may not support some commands. In that case, the operation will fail with a Hamlib error message.

Here is a summary of the supported commands (In the case of set commands the quoted italicized string is replaced by the value in the description. In the case of get commands the quoted italicized string is the key name of the value returned.):

F, set_freq 'Frequency'
    Set 'Frequency', in Hz.

    Frequency may be a floating point or integer value.

f, get_freq
    Get 'Frequency', in Hz.

    Returns an integer value and the VFO hamlib thinks is active. Note that some rigs (e.g. all Icoms) cannot track current VFO so hamlib can get out of sync with the rig if the user presses rig buttons like the VFO. rigctld clients should ensure they set the intended VFO or use vfo mode.

M, set_mode 'Mode' 'Passband'
    Set 'Mode' and 'Passband'.

    Mode is a token: ‘USB’, ‘LSB’, ‘CW’, ‘CWR’, ‘RTTY’, ‘RTTYR’, ‘AM’, ‘FM’, ‘WFM’, ‘AMS’, ‘PKTLSB’, ‘PKTUSB’, ‘PKTFM’, ‘ECSSUSB’, ‘ECSSLSB’, ‘FA’, ‘SAM’, ‘SAL’, ‘SAH’, ‘DSB’.

    Passband is in Hz as an integer, -1 for no change, or ‘0’ for the radio backend default.

    Note: Passing a ‘?’ (query) as the first argument instead of a Mode token will return a space separated list of radio backend supported Modes. Use this to determine the supported Modes of a given radio backend.

m, get_mode
    Get 'Mode' and 'Passband'.

    Returns Mode as a token and Passband in Hz as in set_mode above.

    In VFO mode (see --vfo option above) only a single VFO parameter is required:

        $ rigctl -m 229 -r /dev/rig -o
        Rig command: V
        VFO: VFOB
        Rig command:

v, get_vfo
    Get current 'VFO'.

    Returns VFO as a token as in set_vfo above.

J, set_rit 'RIT'
    Set 'RIT'.

    RIT is in Hz and can be + or -. A value of ‘0’ resets RIT (Receiver Incremental Tuning) to match the VFO frequency.

    Note: RIT needs to be explicitly activated or deactivated with the set_func command. This allows setting the RIT offset independently of its activation and allows RIT to remain active while setting the offset to ‘0’.

j, get_rit
    Get 'RIT' in Hz.

    Returned value is an integer.

Z, set_xit 'XIT'
    Set 'XIT'.

    XIT is in Hz and can be + or -. A value of ‘0’ resets XIT (Transmitter Incremental Tuning) to match the VFO frequency.

    Note: XIT needs to be explicitly activated or deactivated with the set_func command. This allows setting the XIT offset independently of its activation and allows XIT to remain active while setting the offset to ‘0’.

z, get_xit
    Get 'XIT' in Hz.

    Returned value is an integer.

T, set_ptt 'PTT'

i, get_split_freq
    Get 'TX Frequency', in Hz.

    Returns an integer value.

    TX Passband is in Hz as an integer, or ‘0’ for the radio backend default.

    Note: Passing a ‘?’ (query) as the first argument instead of a TX Mode token will return a space separated list of radio backend supported TX Modes. Use this to determine the supported TX Modes of a given radio backend.

x, get_split_mode
    Get 'TX Mode' and 'TX Passband'.

    Returns TX Mode as a token and TX Passband in Hz as in set_split_mode above.

Y, set_ant 'Antenna'
    Set 'Antenna' number (‘0’, ‘1’, ‘2’, ...).

    Option depends on rig..for Icom it probably sets the Tx & Rx antennas as in the IC-7851. See your manual for rig specific option values. Most rigs don't care about the option.

    For the IC-7851 (and perhaps others) it means this:

        1 = TX/RX = ANT1
        2 = TX/RX = ANT2
        3 = TX/RX = ANT3
        4 = TX/RX = ANT1/ANT4

    Get misc information about a specific vfo.

dump_state
    Return certain state information about the radio backend.

1, dump_caps
    Not a real rig remote command, it just dumps capabilities, i.e. what the backend knows about this model, and what it can do.

    TODO: Ensure this is in a consistent format so it can be read into a hash, dictionary, etc. Bug reports requested.

    Note: This command will produce many lines of output so be very careful if using a fixed length array! For example, running this command against the Dummy backend results in over 5kB of text output.

    VFO parameter not used in 'VFO mode'.

2, power2mW 'Power [0.0..1.0]' 'Frequency' 'Mode'
    Returns 'Power mW'.

    Converts a Power value in a range of 0.0...1.0 to the real transmit power in milli-Watts (integer).

    'Frequency' and 'Mode' also need to be provided as output power may vary according to these values.

    VFO parameter is not used in VFO mode.

4, mW2power 'Power mW' 'Frequency' 'Mode'
    Returns 'Power [0.0..1.0]'.

    Converts the real transmit power in milli-Watts (integer) to a Power value in a range of 0.0 ... 1.0.

    VFO parameter is not used in VFO mode.

set_clock 'DateTime'
    Set 'DateTime'

    Sets rig clock -- note that some rigs do not handle seconds or milliseconds. If you try to set that you will get a debug warning message. Format is ISO8601.

        YYYY-MM-DDTHH:MM:SS.sss+ZZ (where +ZZ is either -/+ UTC offset)
        YYYY-MM-DDTHH:MM:SS+ZZ
        YYYY-MM-DDTHH:MM+ZZ
        YYYY-MM-DD (sets date only)

get_clock
    Get 'RigTime'

    Gets rig clock -- note that some rigs do not handle seconds or milliseconds. Format is ISO8601 YYYY-MM-DDTHH:MM:SS.sss+ZZ where +ZZ is either -/+ UTC offset

chk_vfo
    Returns “1\n” (single line only) if rigctld was invoked with the -o/--vfo option and “0\n” if not.

    When in VFO mode the client will need to pass 'VFO' as the first parameter to set or get commands. VFO is one of the strings defined in set_vfo above.

set_vfo_opt 'Status'
    Set 'Status'

    Set vfo option Status 1=on or 0=off This is the same as using the -o switch for rigctl and ritctld. This can be dyamically changed while running.

set_lock_mode 'Locked'
    Turns mode lock on(1) or off(0) (only when using rigctld). Turning on will prevent all clients from changing the rig mode. For example this is useful when running CW Skimmer in FM mode on an IC-7300. Clicking spots in a spotting program will not change the VFOA mode when lock is on. So "set_lock_mode 1" when CW Skimmer is started and "set_lock_mode 0" when CW Skimmer is stopped.

get_lock_mode
    Returns current lock mode status 1=On, 2=Off (only useful with rigctld)

PROTOCOL
There are two protocols in use by rigctld, the Default Protocol and the Extended Response Protocol.

The Default Protocol is intended primarily for the communication between Hamlib library functions and rigctld (“NET rigctl”, available using radio model ‘2’).

The Extended Response Protocol is intended to be used with scripts or other programs interacting directly with rigctld as consistent feedback is provided.

  Default Protocol
The Default Protocol is intentionally simple. Commands are entered on a single line with any needed values. In practice, reliable results are obtained by terminating each command string with a newline character, ‘\n’.

Example set frequency and mode commands (Perl code (typed text shown in bold)):

    print $socket "F 14250000\n";
    print $socket "\\set_mode LSB 2400\n";   # escape leading '\'

A one line response will be sent as a reply to set commands, “RPRT x\n” where x is the Hamlib error code with ‘0’ indicating success of the command.

Responses from rigctld get commands are text values and match the same tokens used in the set commands. Each value is returned on its own line. On error the string “RPRT x\n” is returned where x is the Hamlib error code.

Example get frequency (Perl code):

    print $socket "f\n";
    "14250000\n"

Most get functions return one to three values. A notable exception is the dump_caps command which returns many lines of key:value pairs.

This protocol is primarily used by the “NET rigctl” (rigctl model 2) backend which allows applications already written for Hamlib's C API to take advantage of rigctld without the need of rewriting application code. An application's user can select rotator model 2 (“NET rigctl”) and then set rig_pathname to “localhost:4532” or other network host:port (set by the -T/-t options, respectively, above).

  Extended Response Protocol
The Extended Response protocol adds several rules to the strings returned by rigctld and adds a rule for the command syntax.

1. The command received by rigctld is echoed with its long command name followed by the value(s) (if any) received from the client terminated by the specified response separator as the first record of the response.

2. The last record of each block is the string “RPRT x\n” where x is the numeric return value of the Hamlib backend function that was called by the command.

3. Any records consisting of data values returned by the radio backend are prepended by a string immediately followed by a colon then a space and then the value terminated by the response separator. e.g. “Frequency: 14250000\n” when the command was prepended by ‘+’.

4. All commands received will be acknowledged by rigctld
 with records from rules 1 and 2. Records from rule 3 are only returned when data values must be returned to the client.

An example response to a set_mode command sent from the shell prompt (note the prepended ‘+’):

    $ echo "+M USB 2400" | nc -w 1 localhost 4532
    set_mode: USB 2400
    RPRT 0

In this case the long command name and values are returned on the first line and the second line contains the end of block marker and the numeric radio backend return value indicating success.

An example response to a get_mode query:

    $ echo "+\get_mode" | nc -w 1 localhost 4532
    get_mode:
    Mode: USB
    Passband: 2400
    RPRT 0

    Note: The ‘\’ is still required for the long command name even with the ERP character.

In this case, as no value is passed to rigctld, the first line consists only of the long command name. The final line shows that the command was processed successfully by the radio backend.

Invoking the Extended Response Protocol requires prepending a command with a punctuation character. As shown in the examples above, prepending a ‘+’ character to the command results in the responses being separated by a newline character (‘\n’). Any other punctuation character recognized by the C ispunct() function except ‘\’, ‘?’, or ‘_’ will cause that character to become the response separator and the entire response will be on one line.

Separator character summary:

‘+’ Each record of the response is appended with a newline (‘\n’).

‘;’, ‘|’, or, ‘,’
    Each record of the response is appended by the given character resulting in entire response on one line.

    These are common record separators for text representations of spreadsheet data, etc.

‘?’ Reserved for help in rigctl.

‘_’ Reserved for get_info short command

‘#’ Reserved for comments when reading a command file script.

    Note: Other punctuation characters have not been tested! Use at your own risk.

For example, invoking a get_mode query with a leading ‘;’ returns:

    get_mode:;Mode: USB;Passband: 2400;RPRT 0

Or, using the pipe character ‘|’ returns:

    get_mode:|Mode: USB|Passband: 2400|RPRT 0

And a set_mode command prepended with a ‘|’ returns:

    set_mode: USB 2400|RPRT 0

Such a format will allow reading a response as a single event using a preferred response separator. Other punctuation characters have not been tested!

The following commands have been tested with the Extended Response protocol and the included testctld.pl Perl script:

    set_freq, get_freq, set_split_freq, get_split_freq, set_mode, get_mode, set_split_mode, get_split_mode, set_vfo, get_vfo, set_split_vfo, get_split_vfo, set_rit, get_rit, set_xit, get_xit, set_ptt, get_ptt, power2mW, mW2power, dump_caps.

DIAGNOSTICS
The -v, --verbose option allows different levels of diagnostics to be output to stderr and correspond to -v for BUG, -vv for ERR, -vvv for WARN, -vvvv for VERBOSE, or -vvvvv for TRACE.

A given verbose level is useful for providing needed debugging information to the email address below. For example, TRACE output shows all of the values sent to and received from the radio which is very useful for radio backend library development and may be requested by the developers.

EXAMPLES
Start rigctld for a Yaesu FT-920 using a USB-to-serial adapter and backgrounding:

    $ rigctld -m 1014 -r /dev/ttyUSB1 &

Start rigctld for a Yaesu FT-920 using a USB-to-serial adapter while setting baud rate and stop bits, and backgrounding:

    $ rigctld -m 1014 -r /dev/ttyUSB1 -s 4800 -C stop_bits=2 &

Start rigctld for an Elecraft K3 using COM2 on MS Windows:

    $ rigctld -m 2029 -r COM2

Connect to the already running rigctld and set the frequency to 14.266 MHz with a 1 second read timeout using the default protocol from the shell prompt:

    $ echo "\set_freq 14266000" | nc -w 1 localhost 4532P

Connect to a running rigctld with rigctl on the local host:

    $ rigctl -m2

SECURITY
No authentication whatsoever; DO NOT leave this TCP port open wide to the Internet. Please ask if stronger security is needed or consider using a Secure Shell (ssh(1)) tunnel.

As rigctld does not need any greater permissions than rigctl, it is advisable to not start rigctld as “root” or another system user account in order to limit any vulnerability.

BUGS
The daemon is not detaching and backgrounding itself.

No method to exit the daemon so the kill(1) command must be used to terminate it.

Multiple clients using the daemon may experience contention with the connected radio.
