    Abstract: A communication system comprises a plurality of speech communication terminals each having apparatus for inputting data representing a station. A call is issued in accordance with the data from the communication terminal, and the system receives call data representing a station which responds to the call. The data received by the system is compared with the data input from the speech communication terminal and display units of the speech communication units are controlled in accordance with the comparison result.

    Abstract: A data communication apparatus having an error retransmission mode allows the operator to ascertain an amount of error data when an error is contained in data and when the error is not corrected despite retransmission of the error a predetermined number of times, or makes it possible to reproduce data with respect to correctly received data by discriminating correct data contained in error data, thereby preventing error data from becoming wasted as practically as possible. In addition, at the time of error retransmission, a transmission mode for retransmitting the error data is changed so as to minimize the number of incidents of error retransmission, thereby to enable efficient data transmission.
