1. A peripheral device for use with a data processing apparatus having an interface means for communicating with a peripheral device with any of communication modes of a clocked parallel type, a clocked serial type, a three-wire handshake type and a TH/TR selection type, said interface means including a socket connector with a set of socket pins, comprising:

  • a plug connector detachably connectable to the socket connector, said plug connector having a set of plug pins disposed in a row and corresponding to the socket pins, said plug pins including a pair of first pins for connecting to fixed potentials, a plurality of second pins for conducting data signals, and a pair of third pins for receiving a control signal;

    means for configuring said plurality of second pins to be indicative of a communication mode of the peripheral device; and

    a cable including a plurality of wires connecting the plug pins with terminals on a printed circuit board of said peripheral device;

    said configuration means comprising means for supplying a data signal including identification data representing the communication mode of said peripheral device on said plurality of second pins in response to a first control signal supplied via said pair of third pins from said apparatus for requesting the identification data; and

    means for supplying said apparatus with a data signal including manipulation data via at least one of said plurality of second pins in response to a second control signal supplied from said apparatus via at least one of said pair of third pins.
