if COMPORT rts/dtr is used to toggle ptt, the first program to 'claim' the comport has it locked down and no other program can use it.
There's no com port specified in the VARA port in BPQ, however, only "PTT DTR" as one example.
so if running vara alongside soundmodem on the same radio port, one or the other will not be able to ptt.
letting bpq handle ptt solves that problem.
I can see that working if CAT control is used for PTT, but I'm not seeing how BPQ knows what COM port is being used for PTT (with RTS or DTR).
In my case I'm using a serial port splitting program to allow QtSM and VARA to use the same serial port for PTT.

NOW, if you have a MODIFIED cm108 dongle, the gpio pin is used to toggle ptt and is NOT locked by whatever program uses it first.
so that setup, you can have each program toggle ptt on its own.
Yes, that worked for me when I was using external sound instead of a built-in sound card, but I used INTERLOCK so that BPQ would prevent VARA and QtSM from colliding.?
op has a serial cable for cat/ptt and a non modified dongle (no ptt line available) setup.
If you are referring to NP4JN in the other thread, yes, that was not clear in the first message posted.
