Abstract
A control method for controlling a facsimile communication between a transmitter and a receiver is provided. During protocol procedure, information including decoding speed and capacity of a buffer memory is supplied from the receiver to the transmitter. Then, during data transmission, the transmitter controls the encoding speed to be equal to or smaller than the decoding speed at the receiver by inserting an appropriate number of fillbits, and the encoding operation is interrupted, resumed or a predetermined number of fillbits are inserted depending upon the number of bits stored in the buffer memory of the receiver.
