Personal computers that operate unattended at night using Norstback or Central Point back-up software or broadcast long lists of facsimile letters no longer need to stay on all night long after their work is done: a computer-activated power module that sits in-line between a wall outlet and power strip and accepts signals from a personal computer to control power-flow on and off to the power strip, has been announced in Santa Clara by Server Technology Inc, supplier of remote power control devices and resource sharing networks; the Intelligent Power Module is activated by receiving on or off signals from a personal computer via a cable to the computer’s parallel or serial port; the user simply writes in the power off command at the end of the MS-DOS batch file used to run the unattended operations; priced at $60 it ships complete with software commands on floppy, and the cable.
