Re: The big red button

A client had a SCO box on a UPS with a serial link to start a shutdown. I can't remember the details but doing something which shouldn't have touched the UPS at all started the count down to power-off. The phenomenon was repeatable. I was never able to resolve it but it seemed as if something in the IP stack was also affecting the serial link.
