ABSTRACT:
A communication terminal device (F) having an error correction function defined in ITU-T Recommendations T.30. The communication terminal device includes a modem (3) that can transmit data to a remote device in accordance with a plurality of modulation methods and communication speeds. A controller (1) associated with the terminal device (F) changes a current modulation method of the modem (3) to a different modulation method when an all-frame-error is detected predetermined times during data transmission. The controller (1), however, maintains the current modulation method and reduces a communication speed when a frame error other than the all-frame-error is detected prescribed times.
