SmartSDR CAT Commands?

Problem – Operators at a multi-operator remote station occasionally forget to put the amplifier into standby before hitting the tune button to tune to antenna tuners.  This risks damage to the amplifiers.  The radios are a 6300 and a 6700.

Proposed solution – I want to create a desktop application that would be used instead of clicking on the TUNE button in SmartSDR.  The application would have three buttons – Start Tune, Stop Tune, Operate.  The sequence would be when Start Tune is pressed a command to SmartSDR CAT would – set tune power to 20 watts, disable RCA TX1, and put the radio into tune mode.  Stop Tune would put the radio out of tune mode.  Operate would set tune power to zero watts and enable RCA TX1.

Question – What are the CAT commands for setting tune power, putting the radio into and out of tune mode, and enabling or disabling RCA TX1?

I am sure there are other ways to do this, but I am not interested in them.  I would just like some help with the SmartSDR CAT commands for these actions.

Thank you in advance,
