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.

[ What is claimed is:] [1.]1. A facsimile apparatus, comprising:a modulation system capable of operating in a first mode communication;signal detecting means for detecting a type of signal being transmitted or received by the modulation system;signal record memory means for storing information identifying a preceding type of detected transmitted or received signal;signal change determining means for comparing the type of detected transmitted or received signal with the stored information to determine if the type of detected transmitted or received signal differs from the preceding type of detected transmitted or received signal;time-out period designating means for designating an optimal time-out period for each type of signal in the first mode communication;timer start means for starting a timer each time the signal change determining means determines that the type of detected transmitted or received signal differs from the preceding type of detected transmitted or received signal; andtime-out determining means for determining if the optimal time-out period elapses after the timer is started.
