Abstract
A communication device includes: a communication unit which receives control data; and a main control unit which controls an operation of the communication device, based on the control data received by the communication unit. The communication device operates in a first standby state where the main control unit stops at least a part of operations and where the communication unit detects only an access to a specific port that designates the communication device as a destination, and in a second standby state where the main control unit can execute the operations and controls the operation of the communication device, based on the control data. The communication unit wakes up the main control unit if an access to the specific port is detected in the first standby state.
