Sure...

In the February 1990 issue of Unix World (Vol VII, No 2) on Page 119
(Rebecca Thomas' "Wizard' Grabbag" column) there was a nice article on 
building your own interface to tie to your UPS.  It contained the code and
the instructions for building this system.  I would guess it'll cost you 
$15-25.00 and 30 minutes (maybe an hour) worth of typing. 

If you run more than one system, this is probably a VERY good way to go.
You can then just build another box and copy the software (you entered it :-)

It is really a simple task -- just a relay the trips DTR and the computer
watches DTR on the serial port...
