.SH NAME
rigctld \- Hamlib TCP rig control daemon
.SH SYNOPSIS
.B rigctld
[\fIOPTION\fR]...
.SH DESCRIPTION
The \fBrigctld\fP program is a NEW \fBHamlib\fP rig control daemon ready for testing
that handles client requests via TCP sockets. This allows multiple user programs to
share one radio (this needs testing). Multiple radios can be controlled
on different TCP ports by use of multiple \fBrigctld\fP processes. The syntax of the
commands are the same as \fBrigctl\fP. It is hoped that \fBrigctld\fP will be
especially useful for client authors using languages such as Perl, Python, PHP,
and others.
.PP
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
.\" \fI<whatever>\fP escape sequences to invoke bold face and italics,
.\" respectively.
\fBrigctld\fP communicates to a client through a TCP socket using text
commands shared with \fBrigctl\fP. The protocol is simple; commands are sent
to \fBrigctld\fP on one line and \fBrigctld\fP responds to "get" commands with
the requested values, one per line, when successful, otherwise, it responds
with one line "RPTR x", where x is a negative number indicating the error code.
Commands that do not return values respond with the line "RPTR x", where x
is zero 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 \fINET rigctl\fP (rig model 2)backend.
.PP
A separate \fBExtended Response\fP protocol extends the above
behavior by echoing the received command string as a header, any returned values
as a key: value pair, and the "RPTR x" string as the end of response marker which
includes the \fBHamlib\fP success or failure value.  See the \fIPROTOCOL\fP
section for details.  Consider using this protocol for clients that will interact
with \fBrigctld\fP directly through a TCP socket.
.PP
Keep in mind that \fBHamlib\fP is BETA level software.
While a lot of backend libraries lack complete rig support, the basic functions
are usually well supported.  The API may change without publicized notice,
while an advancement of the minor version (e.g. 1.1.x to 1.2.x) indicates such
a change.
.PP
Please report bugs and provide feedback at the e-mail address given in the
\fIREPORTING BUGS\fP section.  Patches and code enhancements are also welcome.
.SH OPTIONS
This program follows the usual GNU command line syntax, with long
options starting with two dashes ('-').
.PP
Here is a summary of the supported options:
.TP
.B \-m, --model=id
Select radio model number. See the -l, --list option below.
.TP
.B \-r, --rig-file=device
Use \fIdevice\fP as the file name of the port the radio is connected.
Often a serial port, but could be a USB to serial adapter or USB port device.
Typically /dev/ttyS0, /dev/ttyS1, /dev/ttyUSB0, etc.
.TP
.B \-p, --ptt-file=device
Use \fIdevice\fP as the file name of the Push-To-Talk device using a
device file as described above.
.TP
.B \-d, --dcd-file=device
Use \fIdevice\fP as the file name of the Data Carrier Detect device using a
device file as described above.
.TP
.B \-P, --ptt-type=type
Use \fItype\fP of Push-To-Talk device.
Supported types are RIG (CAT command), DTR, RTS, PARALLEL, NONE.
.TP
.B \-D, --dcd-type=type
Use \fItype\fP of Data Carrier Detect device.
Supported types are RIG (CAT command), DSR, CTS, CD, PARALLEL, NONE.
.TP
.B \-s, --serial-speed=baud
Set serial speed to \fIbaud\fP rate. Uses maximum serial speed from rig
backend capabilities (set by -m above) as the default.
.TP
.B \-c, --civaddr=id
Use \fIid\fP as the CI-V address to communicate with the rig. Only useful for
Icom rigs.
.sp
\fBN.B.\fP: The \fIid\fP is in decimal notation, unless prefixed by
\fI0x\fP for a hexadecimal value.
.TP
.B \-T, --listen-addr=IPADDR
Use \fIIPADDR\fP as the listening IP address. The default is ANY.
.TP
.B \-t, --port=number
Use \fInumber\fP as the TCP listening port. The default is 4532.
.sp
\fBN.B.\fP: As \fBrotctld\fP's default port is 4533, it is advisable to use even
numbered ports for \fBrigctld\fP, e.g. 4532, 4534, 4536, etc.
.TP
.B \-L, --show-conf
List all config parameters for the radio defined with -m above.
.TP
.B \-C, --set-conf=parm=val[,parm=val]*
Set config parameter.  e.g. --set-conf=stop_bits=2
.sp
Use -L option for a list.
.TP
.B \-l, --list
List all model numbers defined in \fBHamlib\fP and exit.
.TP
.B \-u, --dump-caps
Dump capabilities for the radio defined with -m above and exit.
.TP
.B \-o, --vfo
Set vfo mode, requiring an extra VFO argument in front of each appropriate
command (except \fI\\set_vfo\fP!). Otherwise, 'currVFO' is assumed when this
option is not set and an extra VFO argument is not used.  See \fI\\chk_vfo\fP
below.
.TP
.B \-e, --end-marker
Use END marker in rigctld protocol.
.sp
\fBN.B.\fP: This option should be considered obsolete.  Please consider using the Extended
Response protocol instead (see \fIPROTOCOL\fP below).  This option will be removed
in a future Hamlib release.
.TP
.B \-v, --verbose
Set verbose mode, cumulative (see \fIDIAGNOSTICS\fP below).
.TP
.B \-h, --help
Show a summary of these options and exit.
.TP
.B \-V, --version
Show the version of \fBrigctld\fP and exit.
.PP
\fBN.B.\fP Some options may not be implemented by a given backend and will
return an error.  This is most likely to occur with the \fI\-\-set-conf\fP
and \fI\-\-show-conf\fP options.
.PP
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 \fBHamlib\fP error code.
.SH 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 \fIPROTOCOL\fP.
.PP
Since most of the \fBHamlib\fP operations have a \fIset\fP and a \fIget\fP method,
an upper case letter will be used for \fIset\fP methods whereas the
corresponding lower case letter refers to the \fIget\fP method.  Each operation
also has a long name; prepend a backslash to send a long command name.
.PP
Example (Perl): `print $socket "\\\\dump_caps\\n";' to see what the radio's
backend can do
.br
(\fBN.B.\fP: 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 \fBrigctld\fP.  This is a
possible bug, beware!).
.PP
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
\fBHamlib\fP error message.

.sp
\fBN.B.\fP: 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

.sp
Converts a Power value in a range of \fI0.0 ... 1.0\fP to the real transmit
power in milli-Watts (integer).  The \fIfrequency\fP and \fImode\fP also need to
be provided as output power may vary according to these values.
.sp
VFO parameter not used in 'VFO mode'.
.TP
.B 4, mW2power 'Power mW' 'Frequency' 'Mode'
Returns 'Power [0.0..1.0]'
.sp
Converts the real transmit power in milli-Watts (integer) to a Power value in
a range of \fI0.0 ... 1.0\fP.  The \fIfrequency\fP and \fImode\fP also need to
be provided as output power may vary according to these values.
.sp
VFO parameter not used in 'VFO mode'.
.TP
.B w, send_cmd 'Cmd'
Send raw command string to rig.
.sp
For binary protocols enter values as \\0xAA\\0xBB.    Expect a 'Reply' from the
rig which will likely be a binary block or an ASCII string.
.TP
.B chk_vfo
Returns "CHKVFO 1\\n" (single line only) if \fBrigctld\fP was invoked with the
\fI-o\fP or \fI--vfo\fP option, "CHKVFO 0\\n" if not.
.sp
When in VFO mode the client will need to pass 'VFO' as the first parameter to
\fI\\set\fP or \fI\\get\fP commands.  'VFO' is one of the strings defined
for \fI\\set_vfo\fP above.
.SH PROTOCOL
\fBDefault Protocol\fP
.PP
The \fBrigctld\fP protocol is intentionally simple. Commands are entered on
a single line with any needed values. In Perl, reliable results are obtained
by terminating each command string with a newline character, '\\n'.
.sp
Example \fIset\fP (Perl code):
.sp
print $socket "F 14250000\\n";
.br
print $socket "\\\\set_mode LSB 2400\\n";   # escape leading '\\'
.PP
A one line response will be sent as a reply to  \fIset\fP commands,
"RPTR \fIx\fP\\n" where \fIx\fP is the Hamlib error code with '0'
indicating success of the command.
.PP
Responses from \fBrigctld\fP \fIget\fP commands are text values and match the
same tokens used in the \fIset\fP commands. Each value is returned on its own
line.  On error the string "RPTR \fIx\fP\\n" is returned where \fIx\fP is the
Hamlib error code.
.sp
Example \fIget\fP (Perl code):
.sp
print $socket "f\\n";
.br
"14250000\\n"
.PP
Most \fIget\fP functions return one to three values. A notable exception is
the \fI\\dump_caps\fP function which returns many lines of key:value pairs.
.PP
This protocol is primarily used by the \fINET rigctl\fP (rigctl model 2) backend
which allows applications already written for Hamlib's C API to take advantage of
\fBrigctld\fP without the need of rewriting application code.  An application's
user can select rig model 2 ("NET rigctl") and then set rig_pathname to
"localhost:4532" or other network host:port.
.PP
\fBExtended Response Protocol\fP
.PP
An \fIEXPERIMENTAL\fP Extended Response protocol has been introduced into
\fBrigctld\fP as of February 16, 2010.  This protocol adds several rules
to the strings returned by \fBrigctld\fP and adds a rule for the command
syntax.
.PP
1. The command received by \fBrigctld\fP 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 record line of the response.
.PP
2. The last line of each block is the string "RPTR \fIx\fP\\n" where \fIx\fP is
the numeric return value of the Hamlib backend function that was called by the
command.
.PP
3. Any records consisting of data values returned by the rig 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 '+'.
.PP
4. All commands received will be acknowledged by \fBrigctld\fP with lines from
rules 1 and 2.  Lines from rule 3 are only returned when data values must be
returned to the client.
.PP
An example response to a \fI+\\set_mode\fP command (note the prepended '+'):
.sp
$ echo "+M USB 2400" | nc -w 1 localhost 4532
.br
set_mode: USB 2400
.br
RPRT 0
.PP
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 rig backend
return value indicating success.
.PP
An example response to a \fI\\get_mode\fP query:
.sp
$ echo "+\\get_mode" | nc -w 1 localhost 4532
.br
get_mode:
.br
Mode: USB
.br
Passband: 2400
.br
RPRT 0
.PP
In this case, as no value is passed to \fBrigctld\fP, the first line consists
only of the long command name.  The final line shows that the command was
processed successfully by the rig backend.
.PP
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
\fIispunct()\fP function except '\\', '?', or '_' will cause that character to
become the response separator and the entire response will be on one line.
.PP
Separator character summary:
.TP
.B '+'
.br
Each record of the response is appended with a newline ('\\n').
.TP
.B ';', '|', or ','
.br
Each record of the response is appended by the given character resulting in
entire response on one line.
.sp
Common record separators for text representations of spreadsheet data, etc.
.TP
.B '?'
.br
Reserved for 'help' in rigctl short command
.TP
.B '_'
.br
Reserved for \\get_info short command
.TP
.B '#'
.br
Reserved for comments when reading a command file script
.sp
Other punctuation characters have not been tested!  Use at your own risk.
.PP
For example, invoking a \fI;\\get_mode\fP query with a leading ';' returns:
.sp
get_mode:;Mode: USB;Passband: 2400;RPRT 0
.sp
Or, using the pipe character '|' returns:
.sp
get_mode:|Mode: USB|Passband: 2400|RPRT 0
.sp
And a \\set_pos command prepended with a '|' returns:
.sp
set_mode: USB 2400|RPRT 0
.PP
Such a format will allow reading a response as a single event using a prefered
response separator.  Other punctuation characters have not been tested!
.PP
The following commands have been tested with the Extended Response protocol and the
included \fBtestctld.pl\fP script:
.br
\fI\\set_freq\fP    \fI\\get_freq\fP    \fI\\set_split_freq\fP    \fI\\get_split_freq\fP
.br
\fI\\set_mode\fP    \fI\\get_mode\fP    \fI\\set_split_mode\fP    \fI\\get_split_mode\fP
.br
\fI\\set_vfo\fP     \fI\\get_vfo\fP     \fI\\set_split_vfo\fP     \fI\\get_split_vfo\fP

.SH EXAMPLES
Start \fBrigctld\fP for a Yaesu FT-920 using a USB-to-serial adapter and
backgrounding:
.PP
$ rigctld -m 114 -r /dev/ttyUSB1 &
.PP
Start \fBrigctld\fP for a Yaesu FT-920 using a USB to serial adapter while
setting baud rate and stop bits, and backgrounding:
.PP
$ rigctld -m 114 -r /dev/ttyUSB1 -s 4800 -C stop_bits=2 &
.PP
Connect to the already running \fBrigctld\fP, and set current frequency to
14.266 MHz with a 1 second read timeout using the default protocol:
.PP
$ echo "\\set_freq 14266000" | nc -w 1 localhost 4532
.SH DIAGNOSTICS
The \fB-v\fP, \fB--verbose\fP, option allows different levels of diagnostics
to be output to \fBstderr\fP and correspond to -v for BUG, -vv for ERR,
-vvv for WARN, -vvvv for VERBOSE, or -vvvvv for TRACE.
.PP
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.  See the
\fBREADME.betatester\fP and \fBREADME.developer\fP files for more information.
.SH 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 an
