I have seen these cards before. they install in your pc and look like a modem, but you can dial into the card to shutdown , restart or start a computer. has anyone seen this before? I am looking to get one. but I dont know what they are called.
It sounds like you're taling about "wake on modem"-type functionality. Check out some of these links and see if they give you the info you need: http://www.google.com/search?hl=en&lr=&ie=UTF-8&q=%22wake+on+modem%22+&btnG=Search
