# testctld.pl - (C) 2008,2010 Nate Bargmann, n0nb@arrl.net
# A Perl test script for the rigctld program.
#
#
# It connects to the rigctld TCP port (default 4532) and queries the daemon
# for some common rig information and sets some values. It also aims to
# provide a bit of example code for Perl scripting.
#
# This program utilizes the Extended Response protocol of rigctld in line
# response mode. See the rigctld(8) man page for details.

=head1 NAME
testctld.pl - A test and example program for `rigctld' written in Perl.
=head1 SYNOPSIS
testctld.pl [options]
Options:
--host Hostname or IP address of target `rigctld' process
--port TCP Port of target `rigctld' process
--help Brief help message
--man Full documentation
--debug Enable debugging output
=head1 DESCRIPTION
B<testcld.pl> provides a set of functions to interactively test the Hamlib
I<rigctld> TCP/IP network daemon. It also aims to be an example of programming
code to control a radio via TCP/IP in Hamlib.
=head1 OPTIONS
=over 8
=item B<--host>
Hostname or IP address of the target I<rigctld> process. Default is I<localhost>
which should resolve to 127.0.0.1 if I</etc/hosts> is configured correctly.
=item B<--port>
TCP port of the target I<rigctld> process. Default is 4532. Mutliple instances
of I<rigctld> will require unique port numbers.
=item B<--help>
Prints a brief help message and exits.
=item B<--man>
Prints this manual page and exits.
=item B<--debug>
Enables debugging output to the console.
=back
=head1 COMMANDS

m, \get_mode Get mode including passband in Hz
V, \set_vfo Set VFO (VFOA, VFOB, etc.)
v, \get_vfo Get VFO (VFOA, VFOB, etc.)
J, \set_rit Set RIT in +/-Hz, '0' to clear
j, \get_rit Get RIT in +/-Hz, '0' indicates Off
Z, \set_xit Set XIT in +/-Hz, '0' to clear
z, \get_rit Get XIT in +/-Hz, '0' indicates Off
T, \set_ptt Set PTT, '1' On, '0' Off
t, \get_ptt Get PTT, '1' indicates On, '0' indicates Off
S, \set_split_vfo Set rig into "split" VFO mode, '1' On, '0' Off
s, \get_split_vfo Get status of :split" VFO mode, '1' On, '0' Off
I, \set_split_freq Set TX VFO frequency in Hz
i, \get_split_freq Get TX VFO frequency in Hz
X, \set_split_mode Set TX VFO mode including passband in Hz
x, \get_split_mode Get TX VFO mode including passband in Hz
2, \power2mW Translate a power value [0.0..1.0] to milliWatts
4, \mW2power Translate milliWatts to a power value [0.0..1.0]
1, \dump_caps Get the rig capabilities and display select values.
