Abstract

PURPOSE:To decrease the rate of the exclusive use of a circuit by stopping the transmission of data in a block when the specified number of times of NAK signals are transmitted to data in the same block of terminal transmitters, and then by transmitting data in the next block. CONSTITUTION:Transmission side T and reception side R are connected together via telephone circuit L and at transmission side T and reception side R, keyboards KB equipped with ten keys and function keys and displays DP which monitor input data and provide the guide display of the input data in the prescribed format are provided respectively. At transmission side T, data are transmitted, block by block, to reception side R under the control of CPU and when an NAK signal for the same data is transmitted as many times as prescribed, the transmission of the block is stopped to transmit data in the next block. After the completion of the data transmission, numbers of blocks which have not been transmitted are transmitted from either one of transmission side T and reception side R through telephone communication, etc., to decrease the rate of the exclusive use of circuit L.
