A data communication apparatus includes a communication section that performs a pre-communication protocol and transmits data to a destination terminal. A memory stores data and communication parameters corresponding to each destination terminal, the communication parameters being utilized to perform communication with the destination terminal. When data corresponding to a destination terminal data is stored in the memory, a controller performs the pre-communication protocol with the destination terminal, using the stored communication parameters corresponding to the destination terminal. When a communication error occurs in a communication with a particular destination terminal having data stored in the memory, a memory controller deletes communication parameters corresponding to the particular destination terminal from the memory.
