It will do just=20 about anything you need, though it is a bitch to set up (umpteen=20 interrelated config files need to be just right). But more=20 importantly, it has lots of good documentation about cables and such. =20 I found, for example, that the supposedly correct APC cable for my APC=20 BackUPS (one of the semi-dumb ones) was actually missing a line. I=20 made a custom cable, and walla! no more problem. Keep in mind, by the way, that the serial cable is not actually sending=20 serial data (like ascii text, for example). It just raises and lowers=20 the levels of various lines to signal various things. (I know you=20 probably already know that, but just for completeness...) And finally, yes, even the dumb UPS's can sense and communicate the loss=20 and return of AC power, at the very least.
