The Smart-UPS's do more than just tell about power fail. It tells about battery status (charge, load, time before battery fails), and temperature of the UCS among other things. > The Smart-UPS's use some sort of dongle RS232 cable if I remember > correctly, i.e. it's not a normal RS232 cable since it has extra > components in it.

Ahem.. Well. umm.. the Smart-ups cable is just a 3 wire cable with pins 2 4 and 7 (I think ... could be wrong). The PC doesn't communicate with the UPS - only the UPS sends data to the PC (thus no receive pin on the UPS) and a pin for power-fail detection, and a ground :-) > The UNIXware software is SCO version too, I don't think they have > a specific version for any other OS. They have for DOS/NT/Netware too. I believe they also have for some of the larger UNIXes i.e. HP/UX and AIX. I don't see why you couldn't use the SCO version on Linux if you were using the iBCS2 code which allows you to run SCO (COFF) binaries.
