ABSTRACT:
Communication between an application program running on an information processing apparatus and a peripheral device and the communication between the information processing apparatus and a debugging device, used for debugging, is effected using a sole interface provided on the information processing apparatus. A switcher for debugging, including terminals17ato17c, connected to a cable7, terminals18ato18c, connected to a cable8, a terminal16a, connected to a cable6, a controller41connected to terminals17a, 17bfor command and to terminals18a, 18bfor command, and a switch unit43connected to the terminal for test17c, terminal for test18cand to the terminal16a, is used. Based on input information51, from one of the terminals for command17aand18b, the controller41outputs output information52to the other of the terminals for command17aand18b, while also outputting control information57. Based on the control information, switch unit43connects one of the terminal for test17cand the terminal16ato the terminal for test18c.
