The SCO disks are supposedly cpio, but I have not been able to get anything off of them, even after careful examination of the horrendous install script. > Alexis Yushin's upsd at least has a thoughtful and extensible design. > If there are features missing for you, why not try to extend it? I just spent the afternoon working on this. I got a SmartUPS v/s which is a lobotomized SmartUPS. I spent a bunch of time watching the bytes flow between the ups and the os/2 version of powerchute v/s. I added a second type of ups to upsd that seems to work well. The two commands that I don't understand are G and 9. During normal operation powerchute sends the commands Q, 9, and X to the UPS once per second. If the power power goes off, the sequence changes to Q, G, and X. 9 always returns FF while G always returns T. Clues? Also, for someone with a real SmartUPS (or any other APC), does Control-A return a model number? If so, it may be possible to have a more generic APC module. -john == jfieber@indiana.edu =========================================== == http://fallout.campusview.indiana.edu/~jfieber ================
