Thanks to Don's config instructions I finally got SOL working! It took
a while before I stumbled upon the help menu which said that SOL won't
work over COM1. I had to use COM2.

It'll even allow me to reach the BIOS *iff* I get the timing
correctly. Of course on a reboot it goes down the instant eth0 gets
pulled down.
