I haven't used CT with serial port keying for 6 years so the memory is a little hazy. Turns out you can't have the rig control and keying on the same serial port with CT. You can run them on separate serial ports, which is what I did back then. Once I got two K2s I used parallel port keying. You should still be OK with N1MM. Make sure you are connecting your keying interface to pin 4 and 5 at the computer end of the serial cable and only pins 2, 3 and 5 are connected at the KIO2 end of the cable. 73 Gary, N7IR K2 1078, 2154, 3463 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
