Yet another follow-up: Another relevant aspect of my search is any device that would go into a low-power (or sleep) mode and then activate upon receiving data over a network link. So for example, a printer with a print server that sits on a network and stays in an energy saving or low power mode when it's not doing anything but then fires up to print a document when it gets a request. Something like that. I would need documentation explicitly describing this sort of action. I would imagine there is something relevant with network cards that have some sort of power-on feature when network activity is sensed. This would have to be prior to 1994. Solid leads that I can use will be rewarded appropriately.
