We have a Sun 3/280 protected by an AT&T 1kVa UPS.  The UPS has a serial
port to connect to the Sun which can be used to inform the Sun that a
power failure has occured.  At this point Sun should alert all users still
connected and do a system shutdown before the 10 or 15 minute power from
the UPS batteries runs out.  Does anyone have the software for a Sun to
recognize alarm condition and do the shutdown?

[[Ed's Note: There was a lot of talk about UPS systems and software a
while back (Nov '89), however the only software that was explicitly
mentioned was 'upswatch' by Brent Chapman (brent@mica.berkeley.edu). -bdg]]
