[Dx4win] operating CW from keyboard and keyer without unplugging

[Dave Sharred]

Even if both are transistor keying (open collector, same polarity); you still wont have any probelms. the output that is keying wins!

Ed,
I'm not Jim, but I've paralleled my keyer output and serial port 
computer-generated CW for many years.  Just make sure your keyer has an 
isolated output, i.e., a relay (reed or solid state) rather than keying 
directly via a transistor output.
