Ned, If your UPS sends some sort of command string over a serial line, it easy to write a process that would parse the string and trigger a shutdown under A/UX. If the two serial ports of the Mac are already used, you need an additional serial line interface and an A/UX driver for it. Applied Engineering makes async multiplexers and A/UX driver software. You can use the same trick if your UPS sets an output line using a parallel interface NuBus card. National Instruments makes such cards. I don't know about A/UX drivers though. Finally you would have to integrate the shutoff process in /etc/initab so it would be launched when you boot A/UX. I have no ideas if you can buy this stuff ready made. Alberic
