[WL-USERS] Serial PTT-FSK and CW
Wed, 31 Mar 1999 00:30:30 -0500
I've been given lots of interesting interface ideas, most of which are
driven by he parallel port. N1RCT's is the best...use a single serial port
-- TXD (pin 2 of a DB-25 for FSK, and then DTR (pin 20) for cw *and* PTT
when in FSK mode.
My question is whether PTT wired this way will work when I use the SB card
on phone. The WL manual only shows PTT on the parallel port. Radio
control is off a separate comm port.
Thanks in advance,
