Thanks for your replay. Actually my UPS uses a lite version of that software
and only reports mains on/off, ups on/off and ups connected/disconnected
status. I also think the genericups driver should work and tried all the
driver types without any luck. Unfortunately I can't afford to ditch the UPS
right now. I'll try the serial sniffing technique or use a multimeter to
find out what's happening through the serial port. I've some experience with
those. Can you give me some idea what I should be looking for?
One more question. Is it possible to use a USB to serial cable for a serial
UPS with generic UPS driver? This combination works in Windows with the
official software but what about NUT? Is any special configuration required
