I saw this quite recently in "comp.sources.misc".
It may be useful if you want to do automatic shutdown
for power outages that lasts a little too long.
There have been two patches to this.

The UPS monitor daemon or "upsd"  watches the serial port connected to 
an UPS and will perform an unattended shutdown of the system if the UPS 
is on battery longer than a specified number of minutes.  Upsd needs to 
watch a tty with modem control properties, and expects the UPS to raise 
DCD when it switches to battery backup and drop DCD when it goes back to 
online.  Upsd was developed and tested under ISC with the FAS 2.08 driver
and an American Power Convon SmartUPS 600, your milage may
vary on other OSes and UPSes.
