Format of CAT commands for PTT

What is the expected format of the CAT commands for PTT? I tried TX;ff,fe,88,00,1c,00,01,fd

RX;ff,fe,88,00,1c,00,00,fd

I also tried prefacing 0x in front of the hex values, also delimiting with semicolon.

I watched the com port communications and VarAC just sends the same ASCII string as configured out the com port, not the hex/binary.

New message works only when you connect to a station. VarAC is a P2P chatting app. you need to connect someone for a message to be sent out.

Thanks! I installed OmniRig and updated to latest VARA and CQ and station call now transmits. Still no transmit with the "New Message" dialog.

For Icom I need to send a different type of data stream. HEX codes rather then clean text like "TX;". I will need to add functionality to do this and this is indeed on my roadmap... In the meantime I decided to go with OmniRig integration as Omnirig already covers almost all transceivers out there. so I strongly suggest you use OmniRig for now.
