Re: VARA PTT

 

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.

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.

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.

op has a serial cable for cat/ptt and a non modified dongle (no ptt line available) setup.

good luck all,

From the document at

The first line defines the IP address and Port of the VARA TNC, an optional PTT parameter, and an optional PATH to the VARA exe file. If PTT is omitted, VOX operation is assumed.

Given VARA HF has its own PTT settings, why specify PTT in BPQ? For example, I have VARA set to use a serial port on the radio for PTT (using RTS).

My BPQ port for VARA has no PTT specified, and things seem to work fine. In other words PTT is omitted, but it's not using VOX.

Perhaps something changed after the documentation was written?
