Well, I know I need closure, so I figured you may want to know what's goin' on, even tho' you may not like the solution. I don't, but I was out of ideas.
I wrote a VB program that uses 'SendKey' to tell telnet what to do, including login info and the shutdown command. It is triggered by a battery event on the windoze server and shuts down SCO.
I hate it, but it's extremely simple and it's consistent with M$'s crappy way to do things....
