Sorry, nate. I guess that's what I get for working late into the night
and trying to rush myself too much. I can't believe I didn't remember to
drop the zero.
Apparently my serial ports are setup as /dev/ttyS2 and S3. I may have
configured them to use a different irq and/or ioport in the bios, which
could do that, I guess.
Anyway, I'm now successfully playing with the CerfCube, talking through
a serial cable using minicom. A Linux distro. and webserver running on a
three inch cube... technology's wonderful. :-)
Thanks again,
Jacob
