[Tlf-devel] CW Daemon pinout - suggestion

Hello TLFers/CW Daemon users,

I suggest a different pinout for better compatibility with usual
paralle port interfaces. Signal for MIC/Sound card switching on pin 14
is not the best solution. TR/NA/CT employs this pin for radio A/B
switching in SO2R mode or as pullup voltage source for paddle inputs
(attach 10 resitors from pin 14 to pin 12 and pin 14 to pin 13) in
single radio mode.

Therefore, I suggest to move this signal from pin 14 to pin 5 which is
mostly used with TR and SBDVP (by W9CF). BTW SBDVP allows to assign
more different pins to MIC/Sound card switching signal to match actual
configuration.
