Not hard to build I should think. Use the parallel port to drive
a transistor, driving a relay (don't drive the relay directly). You could
put one transistor each on four bits of the parallel port output.
For safety, use two bits and a TTL 2-4 decoder. That ensures mutual
exclusion (you don't want to transmit right into another transceiver's
receiver, I suspect).

Linux can do it. So can FlexNet I hear.

Subject: Software for KPC-3
I picked up some ham equipment recently, including a KPC-3 TNC which was
connected to a dumb Terminal. I would like to find a DOS or Commodore program
that I could use instead. Any help identifying freeware / shareware will be
appreciated. As a last resort, commercial software sources will be
appreciated.
Thanks and 73's

No, sorry. None of the Kantronics gear is TNC2 compatible.
Pac-Comm and MFJ offer TNC2 compatible TNC's, if that's what you need.
