Ted,
You should be using the special cable from the PC (or USB to Serial
adapter).
That cable has no RTS or DTR wires in it, so it will not work for
sending CW from N1MM. In other words, DTR and RTS are not implemented
in the K2.
Do NOT try to "fix" it by plugging the USB to serial adapter directly
into the K2 - if it does not damage the K2, it will cause "strange
happenings" in the K2 operation.
Either a 'one transistor' keying interface, or a K1EL Winkeyer will have
to be used between the USB to serial adapter and the K2 key jack to make
N1MM send CW in the K2.

I need advice for getting N1MM+ to play well with a K2. I have tried it
with two different K2 rigs: a K2 with a KIO2, and a different K2-100 with
the built in IO. Same problem. The K2 Port parameter is set to ON and N1MM
tracks the RX frequency, so I know the rig and the computer are
communicating. But a keyboard command from N1MM to the rig returns the
error message -- "Unable to send this CW because there is no CW Port set in
Config."
