And there is such a thing!  The BEST UPS has a serial port interface to it
that I can/will hook to my Sun 4/280 file server via the ttya port.  I got
some software off the net (and I will be glad to send it to others) that
monitors the UPS.  It was written by Brent Chapman (brent@mica.berkeley.edu)
and is called `upswatch'.

When the UPS kicks in because of power problems, the SUN sees this and
sends out a warning.  When there is less then some threshhold of time's
worth of power left on the UPS's batteries, then the system is
automatically shutdown.  The whole thing runs as a daemon, so you just
start it up in rc.local.
