[WriteLog] RigControl & Soundcard PTT/FSK on same port?

[k0bx@qsl.net (k0bx@qsl.net)]

If I only have one (1) RS-232 port can I connect rig control and
soundcard
interface to the same port?

I thought I had read that someone did this with a 'Y' cable??

It looks like it almost can be done,
9 pin connector

pins (2) TXD and  (3) RXD for rigcontrol

pin (7) RTS or (4) DTR for PTT

But that leaves us without a pin for FSK??

Any Ideas???
