PURPOSE:To automatically recognize a connecting device and to start the corresponding test program just with connection of a device. CONSTITUTION:A device ready interruption AVR (1) is carried out with application of e power supply, etc., when a device 1 is newly connected. Then the OS that received the interruption AVR (1) produces a sense command to the connected device to collect the information on the device 1. Thus the OS generates a unit control block UCB of the device 1, e.g. the connection, the application of power supply, the address, etc., of the device 1 (2). Then the OS selects the corresponding test program TP (3) based on the block UCB and executes the program TP. Thus the normalcy of the device 1 is confirmed. |
