Bob, I'm using for years CW Com port keyer with many versions of DXB, recently moved it to LPT port (needed COM for another purposes), works flawlessly, same as with N1MM. You can't use the same port for controlling the rig via DXB and for CW, it MUST be a separate ports. Stupid question: did you built in the keying circuit (transistor+resistor)? Barefoot COM can't drive the keyer input of your TRX... 73!
