Different terminal equipment is identified on the basis of a program provided on the side of the host unit and on the basis of data transaction with the hardware of the terminals. To this end, a microprogram is transferred from the host computer to the terminals, while the result of execution of the microprogram determined on the basis of the types of the terminals and components thereof is transferred to the host computer from the terminal. In this way, confidential security is assured between the host and the terminals. | |
