I did not write that. Please keep your attributions straight. I wrote a response which contained that text, but that was written by someone else. 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. Once you have one of those cables its some sort of 1 or 2 letter commands sort of thing to get info out of the UPS. It's the cables that hurt since they cost more than a simple 232 cable. Hm. I thought that they told me it was normal serial... If this is true, I'll have to manufacture a cable myself. Won't be the first time... The UNIXware software is SCO version too, I don't think they have a specific version for any other OS. They appear to have at least two different versions, since I've seen them for two different prices... I didn't buy it; I don't want software to which I don't have the source controlling when I shut my machine down, even if I *can* run it. Thanks for the info. I ordered my Smart-UPS 900 yesterday, and it will arrive next week, baring disaster. Then I get to work on it... michaelkjohnson
