[Elecraft] N1MM & K3

[Vic K2VCO]

I'm not the one who originally asked the question, but it's true that some USB adapters 
may not work properly with this function. I have a real serial port on my computer, and 
have had very good luck generating CW directly from N1MM.

But YMMV, especially with USB adapters.
