[WT-support] Stopping a station from sending

[Bob Wilson, N6TV]

Tom,

I can't say that I understand exactly what you need, but could you use any
of the documented printer port pins for this?  See

http://docs.win-test.com/wiki/Menu:Options#Printer_Ports

For example, pin 16 (PTT) is held down for as long as Win-Test has queued
data to send.

73,
