A data communication system in which parameter values for data communication can be set at optimum values for data errors. When receiving data formed in a frame structure, the receiving terminal finds the number of errors in the received data. When failing to detect the number of errors, it calculates an approximation of the number of errors from a past error rate. The receiving terminal also calculates an error rate on the basis of the number of errors or the approximation therefor and informs the calculated error rate to a transmitting terminal. The transmitting terminal changes the set values of parameters including frame length of data of the frame structure to be transmitted on the basis of the informed error rate. The receiving terminal finds the number of burst errors generated within the received data, calculates a random error number by subtracting the burst error number from the total error number, and informs the transmitting terminal of the random error number, while the transmitting terminal changes the set values of parameters including frame length of the frame-structured data to be transmitted on the basis of the informed random error number.
