Abstract
A facsimile apparatus including a modulation system capable of operating in V. 8 and V. 34 mode communication. The apparatus also includes a signal detect device that detects a signal being transmitted or received by the modulation system, and a signal change determining device which determines if the detected transmitted or received signal differs from a preceding detected transmitted or received signal. A timer start device starts a timing device each time the detected transmitted or received signal differs from the preceding detected transmitted or received signal. If a time-out determining device determines that a prescribed period of time has elapsed after the timing device is started, an error record memory device stores a record indicating that the prescribed period of time has elapsed. An error record device can then output the information in the record stored in the error record memory device.
