Hi, I've never dealt directly with UPS, but from my experience with with serial ports, you typically send the hardware a signal in the form of a hex code that tells the device what to do. With this in mind, you'll need the technical manual of the UPS provided by it's manufacturer for the hex codes (or whatever the device uses). Let's just hope it's available to the public so you don't have to tinker with the circuitry itself. -Paul -- Philippine Linux Users' Group (PLUG) Mailing List [EMAIL PROTECTED] (#PLUG @ irc.free.net.ph) Official Website: http://plug.linux.org.ph Searchable Archives: http://marc.free.net.ph .
