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.

-for Icom 7100

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.
