Rig control of audio ouput level (new feature request)

[ve7it]

Hello,
I have been working on a remote control program in C that works across the TCP link into SDRPP. I have successfully been able to set frequency, mode and bandwidth. Looking at the SDRPP server source, it appears there is no way to set the volume through the TCP interface. I would like to see a rig control command implemented that adjusts the audio output level (same actions as the user moving the volume slider on the top of the SDRPP window). I am not sure if there is a standard rig control command available for volume output, but it seems like it is a reasonable addition for remote operation. "V" and "v" are already used for selecting and requesting VFO. Volume settings between 0 and 100% probably make sense.

Does this seem like a good addition to SDRPP?

My cpp foo is not great, but following the set bandwidth code, it seems like remote control of the volume slider should not be a difficult addition. In a similar manner, remote control of squelch level could be useful for implementing remote radio front panels.
