Adding Cyber Power 1500AVR UPS Monitoring to my Fedora

Oi! Yet another note set for my Fedora machine. This time I'm trying to configure support for smart UPS monitoring so if there's a power outage, the machine will shut itself down while the UPS has enough juice.

Some details:

1. OS: Fedora Core 3 - heavily customized
2. System Board: Tyan Tiger MPX, Serial port 2
3. UPS: Cyber Power Systems 1500AVR
