Ok, I got ahold of a 6-prong telephone cable, clipped the tab, and
soldered connected it to a DB25 cable using the following pinout:

Wire# Signal Color Destination/25pin plug

1 DTR White 20
2 TXD Black 2
3 GND Red 7
4 Com Green 8
5 RXD Yellow 3
6 DSR Blue 6


Still, I can get absolutely nothing to display on the terminal. My
solder job is horrible, but I don't believe so bad as complete stop the
connection. I've tried booting the system with the S3 switch in both
places and with and without a null modem adapter in place (do I need one?).

Any suggestions as to what I should try next?

Thanks,
Tom
