Abstract
To control an information processing system in which a host unit is connected by radio communication to a slave unit, the host unit transmits data and a selected one of plural carrier waves both containing ID information to select a specific information process. The slave unit recognizes the ID information which corresponds to the frequency of the selected carrier wave and performs its operation accordingly. A difference in frequencies of the carrier waves may be used as a type of ID information.
