[Elecraft] k3 and n1mm comm problem

Recent versions of N1MM Logger seem to have problems with serial port CW 
keying via the K3's radio control port, at least when that port is a USB 
adapter. Try setting DTR and RTS both to Always Off and unchecking the 
CW/Other box beside the port in the N1MM Configurer to see if that gets 
your radio control working.

You might also try different speeds. The USB adapter may work better at 
higher speeds. I use 38400 baud with a Prolific adapter with no 
problems, provided I don't try to do radio control and CW keying on the 
same port (either one alone works fine, but trying both together 
produces very similar symptoms to the ones you describe).

If this solves the connection problem, you may have to consider using a 
second USB port for CW, in which case the optimal solution would 
probably be a WKUSB.
