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?
