Data communication apparatus

A data communication apparatus comprising:

• a communication section that performs a pre-communication protocol with a destination terminal, and transmits data to the destination terminal after the pre-communication protocol;
• a memory that stores data corresponding to at least one destination terminal, and communication parameters corresponding to each destination terminal, the communication parameters being utilized to perform a communication with the destination terminal;
• a controller that, when data corresponding to a destination terminal data is stored in said memory, performs the pre-communication protocol with the destination terminal, using the stored communication parameters corresponding to the destination terminal;
• and
• a memory controller that, when a communication error occurs in a communication with a particular destination terminal having data stored in said memory, updates the stored communication parameters of the particular destination terminal with communication parameters newly acquired from the particular destination terminal under a normal protocol.

A data communication apparatus comprising:

• a communication section that includes a modem, that performs a pre-communication protocol with a destination terminal, and that transmits data to the destination terminal after the pre-communication protocol;
• a memory that stores data corresponding to at least one destination terminal, and modem parameters corresponding to each destination terminal, the modem parameters being utilized to perform a communication with the destination terminal;
• a controller that, when data corresponding to a destination terminal data is stored in said memory, performs the pre-communication protocol with the destination terminal, using the stored modem parameters corresponding to the destination terminal;
• and
• a memory controller that, when a communication error occurs in a communication with a particular destination terminal having data corresponding to the destination terminal stored in said memory, deletes modem parameters corresponding to the particular destination terminal from said memory.
