I also forgot to mention that some UPS used to have a serial port on them 
to provide a means to notify a computer of a power fail allowing automatic 
system shutdown. Most computers no longer include a serial port. Modern 
USP's may provide some other way (USB or ethernet) to sent the power fail 
notification to an external computer system.
