Abstract: A system for controlling exchange of information between a personal computer (PC) and two peripheral devices coupled to the PC through a single common PS/2 port of the PC comprising: a computer mouse having a standard functionality and including radio enabling components coupled to the single common PS/2 port, an enhanced mouse driver incorporated in the PC and operative to perform an enhanced protocol that facilitates bidirectional exchanges of information between the radio enabling components and the PC while maintaining said standard functionality of said computer mouse, and an enhanced microcontroller incorporated in the computer mouse and operative to control the bidirectional exchanges of information through the enhanced protocol.

Abstract: A system for the combined input of data into a personal computer and for reception of wireless radio-frequency signals uses the PS/2 mouse interface for radio control in a way that does not interfere with normal mouse operation. The system includes both hardware and software. The hardware can be an integrated device with both computer mouse and radio capabilities united in one physical unit, or a non-integrated device comprised of separate mouse and radio units. In both integrated and non-integrated embodiments, the device is connected to a PS/2 port of the computer. The system uses an enhanced protocol for combined data input into the computer and for radio features, and includes a special mouse driver used for performing the enhanced protocol.
