Mike another option that I did not see in Guy's note is an "Null Modem
Adaptor/Dongle" that plugs in at either end of the standard serial cable
they come in 9 and 25 pin flavors as well as many gender combinations.
This way down the road you wont have to worry about the internal wiring of
any given cable.  I have been using these Adaptor/Dongles for years now and
really does help in the sanity maintenance department for this fuzzy ol

Good luck and look forward to working you during FD as well
