[Elecraft] RS232 cable source

[Don Wilhelm]

Bill,

Get yourself a standard computer serial cable - straight thru wiring. 
You do NOT want a null modem cable or a crossover cable.

The only signals that are required for K2 communications and firmware 
downloads are TXD and RXD (plus signal ground), but some applications 
also provide keying and PTT functions on the RTS and DTR signalling 
lines, and the K3 will respond to those if the cable has those lines 
present (the normal serial cable does have thes lines).
