I've also wondered if an old PCI modem card might be used in various
ways. Mimicking a "ring in" in many cases can be configured to wake a
system and is probably very widely supported from what I've seen of
Many of the modem cards have a relay that might also be switched by
sending modem commands. The relay outputs can be commandeered to some
useful purposes, e.g. being the initiating switch to powering all other
