For my systems in house and a couple of other projects I've been considering 2 projects. 1. Watchdog card, or box of some sort 2. Reset controller box serial input [ modem maybe ] with 8 relays to allow the reset of computers remotely Is there a demand for these sorts of hardware ? Wish lists for features ? I will be doing the reset controller box, for my own use at some point soon, making a small board that could be mounted in a box or in the equipment rack. The watchdog card is a possibility but not as useful for me, but maybe moresuitable for others. Ideas and gotcha would be welcome. -- Peter Sleggs VA3SLE Bellatrix Systems Corp. peters@belsys.com
