I remember what the problem was that made me use three com ports. It
was that I wanted to be able to use MMTTY as a stand alone program. It
is MMTTY that conflicts the com port lines with WriteLog. MMTTY uses
both RTS and DTR for PTT, where WriteLog uses DTR for CW keying and RTS
for PTT. So if you connect the DTR pin to the CW jack on the rig, MMTTY
keys the CW jack every time you transmit RTTY. On some rigs that may
not be a problem, but on mine it causes the CW sidetone to be present
during RTTY transmission.
If there is a way around this, please let me know. I spent hours on it
and never could find a fix, other than the additional com port.
