Joe, I have the same problem. Was trying to switch over to using a serial
port instead of a parallel port, but I get a continuous tone (keying). Going
back to a parallel port keying till I can figure this out.

Well, thanks to Ron, KA9ALS, I've now learned to turn on the LPT/COM RTS
setting. Now the interface keys continuously again. This time I haven't
reversed the emitter and collector, so I'm not sure what's going on. Will
ponder that at lunch.
