There are many ways to make a null modem cable, but here's one that
should work for most applications.  I assume you have standard RS-232
25 pin D-type connectors on both ends.  Otherwise you'll have to
translate the wire list for your own connectors.

1 - 1
2 - 3
3 - 2
4 - 5
5 - 4
6,8 - 20
7 - 7
20 - 6,8

Basically, this crosses data transmit and receive, CTS/RTS,
DSR/DTR, and gives you a carrier detect indication as well.
