Abstract: PURPOSE: To automatically perform initialization at power-up time by making the docking possible portable computer system visible to a user. CONSTITUTION: A base unit 1 includes an RS232C connector 7, a parallel port connector 8, a telephone jack connector, and an Internal circuit device 10 which operates through those connectors, and a docking unit 2 also includes connectors and relative circuits like those. An internal logical communication path comx can be allocated to those connectors and relative circuits. When both the units are docked, the path operates without any contradiction and when the base unit is not docked, all internal paths in the base unit are sufficiently utilized.
