Okay, what you need is a 'special' cable to connect 'pin x' at the UPS-port to some 'pin y' at the computers port. But the pins are very well described in the Owner's manual that comes with the UPS (or did they change their policy ?-- i bought my UPS in 1993). According to this manual, there is a pin to turn off the UPS, one to signal a transfer to battery backup, one to signal if less than 2 minutes of backup time left (can be changed to 5 min) and one to turn on the UPS. I think this is more than required to write a simple UPS - watching program. Holger
