BACK-UPS uses the the RS-232 control lines to transmit information about the state of the UPS (on battery, on line power, battery low). So your cable has to have those wired up proerly. I suspect you'll have to either make a cable, or order one of the UPS cables. It's all documented in the nut documentation, including diagrams of the various different cable layouts. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
