As far as I know, straight serial cables won't work (having tried one and changing the gender of one of the plugs).

In theory, a dumb UPS serial cable would detect when the UPS switches from AC to DC when a power failure happens. A "smart" UPS would be able to detect more information. I'm not really that conversant in electrical engineering (how I do wish I took that :D) so any suggestions on how to go about with this? -- Paolo Alexis Falcone [EMAIL PROTECTED]
