Screen can do logging and open windows to serial ports directly by
itself (as I mentioned in my other mail). It's been working very
reliably for me; some my servers are daisy chained together, and
whenever I've had one fail, the one before it has had a log of its
output, even after unattended reboots.

screen is a gem. A soekris and a serial card and openbsd is an
incredible console server for server administration, especially compared
to the dedicated hardware ones.
