It's a Socomec-Sicon EGYS-LP 1000, 1000VA model. Workstation and monitor plugged in. When I turn off the circuit breaker, an alarm sound regularly, and the machine remains powered for approximately 12 minutes before it quits.

I'm not using any software other than the builtin XP control panel-when I looked at it it seemed to fit the bill. Am I wrong?

Wrong, the built-in UPS software included in Windows works only with APC devices. You will need to install the software for your particular non-APC device. Just like a nVidia video card can't use ATI drivers, you need to match the software/driver with the device that it supports. If you look at the drop-down list of available UPS makers, APC is the only one listed. There is a "generic" entry but it probably uses the same communications protocol (commands) and assumes the same serial port pinout for an APC device. Sounds like you really have no software control over the UPS.

UPS'es too often use their own wiring and signal order on those wires. They may provide a serial cable which connects to the COM port on your computer but the other end is not a serial port and the wiring gets changed within the cable (so you also need the matching serial cable provided with the UPS rather than some generic serial cable). With a UPS that uses a standard COM cable, it doesn't matter which end you connect to the computer and UPS, but with a specialized cable then you need to make sure the "UPS" end goes to the UPS and the "COM" end goes to the serial port on the computer. If the UPS provides RJ11 (network) or USB connections, use those instead.
