ABSTRACT:
A communication device such as a facsimile device, in which data is transmitted between a modem and a controller on the basis of interrupt processing, changes the rule associated with the timing of generating an interrupt request from the modem to the controller depending on the transmission rate of the modem, so that data transmission between the modem and the controller can be correctly performed even when the modem performs transmission at a high speed.
