Sure, see the recently posted "upsd" program in comp.sources.misc; it does

It details a very simple hardware project which can provide a power failure
signal for the garden-variety (eg: cheap) UPS and also the software needed
to monitor it.  By combining the information in this article and the
upsd program from comp.sources.misc, anyone should be able to implement
a very nice system like this for a modest cost.  I plan to (when I get
