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).

In anticipation of my K3 arriving next week I'm tying to find the RS232
interface cable. I'm going to be out of town a lot and pressed for shopping
time so I hope nobody minds my asking a dumb question. Where can I get the
needed cable - Best Buy, Radio Shack, Wal-Mart? My K2 will now be at the
lake cabin so that cable goes with it.
