Abstract
A system and method for remotely waking up a device connected to a local area network (LAN) is disclosed. A special data packet is disclosed wherein the destination address of the packet is embedded at least 16 consecutive times within the data field of the packet. When this particular type of packet is transmitted on the LAN, it is first decoded by the I/O subsystem of the device to determine whether or not it is a remote wake-up packet. After determining that the packet received is a remote wake-up packet, a wake-up enable line is activated thereby taking the system out of its low power mode, for providing further processing of future received packets.
