ABSTRACT:
A data communication apparatus can conduct data communication by selecting an appropriate transmission rate in accordance with states of transmitting and receiving apparatus and a line condition.
A transmission rate executable in accordance with an execution state of the process and transmission rates possessed by its own modem are informed to a destination apparatus, and transmission rates possessed by the destination apparatus and an executable transmission rate are received through the modem, and a quality of a line is also detected to determine the transmission rate. The transmission rate is changed in accordance with a change of execution state of the process during the communication.
