ABSTRACT:
A facsimile apparatus performs an effective process in retransmission when a communication based on ITU-T Recommendations V. 8 and V. 34 ends with an error. A retransmission in succession to an error that occurs in the middle of a V. 8 and V. 34 communication is performed in one of the following transmission modes: a mode not performing the V.8 and V. 34 communication, a mode performing V. 8 and V. 34 communication but with a baud rate limited, and a mode performing the V. 8 and V. 34 communication but with a bit rate limited.
