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.
-
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.
-
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.
- -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 radio configuration parameter(s), e.g.
stop_bits=2.
-
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.
- -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, an upper case letter will be used for
set
methods whereas the corresponding lower case letter refers to the
get
method. Each operation also has a long name; prepend a backslash, '\',
to send a long command name.
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'

'DSB'.
-
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 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
'RIT'
in Hz.
-
Returned value is an integer.
- Z, set_xit 'XIT'
-
Set

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'.

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.
-
'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.
- chk_vfo
-
Returns "CHKVFO 1\n" (single line only) if
rigctld
was invoked with the
-o/--vfo
option and "CHKVFO 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.
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.
