Data communication apparatus and data communication method

摘要

A data communication apparatus includes a calling section that performs a communication by sequentially transmitting a calling signal to a destination, and transmitting a shift notification signal that indicates a shift to a short previous-procedure. A memory stores destination information and modem control information in association with each other. When the destination to which the communication is performed corresponds to the destination information stored in the memory, the calling section transmits the shift notification signal, and controls a modem based on the stored modem control information so as to shorten a previous-procedure.
