摘要： An information processing apparatus such as a personal computer is capable of controlling consumption power of a digital communication line interface circuit or a modem depending on a usage state of the communication line. In one aspect, the information processing apparatus including a digital communication interface circuit connected to a digital line to communicate data, includes a link state detect circuit to ascertain a link state between the interface circuit and the communication line and a consumption power mode change circuit to change a consumption power mode change circuit to change a consumption power mode of the interface circuit depending on the link state ascertained by the detect circuit.
