And you can do it with Freeware - CT logging program www.k1ea.com
There is a signal line on LPT that drives a transistor to control a set of
relays to switch the keying line, footswitch, audio and antenna between
the rigs. (or you can use a DXDoubler from TopTen)
NA logging program will do it with the same box from TopTen.
WriteLog will do it with their box.

I have
COM1 - mouse (it's an old P5-133!)
COM2 - Packet
COM3 - left K2
COM4 - right K2
LPT1 - keying

8r hold if you use an external amp.

It's really neat to have the remote antenna switch on the right K2 and a
vertical on the left K2 and switch back and forth.  I'm starting to like
SO2R.
