Abstract:
1. A data communication apparatus that performs a pre-communication protocol with a destination terminal and transmits image data to the destination terminal, the data communication apparatus comprising: a memory configured to store parameters for at least one destination terminal; a controller configured to determine whether or not parameters for a destination terminal are stored in the memory; a communicator configured, when the controller determines that the parameters for the destination terminal are stored in the memory, to perform a short protocol with the destination terminal, using the parameters stored in the memory, and when the controller determines that the parameters for the destination terminal are not stored in the memory, to perform a normal protocol with the destination terminal, obtaining parameters from the destination terminal and using the parameters obtained from the destination terminal in the normal protocol, the communicator being further configured to receive a non-standard facilities signal from the destination terminal during the normal protocol; said controller being further configured to determine whether or not the non-standard facilities signal received by the communicator indicates that the destination terminal can perform the short protocol; and the controller being further configured to store, in the memory, the parameters obtained from the destination terminal when the controller determines that the non-standard facilities signal indicates that the destination terminal can perform the short protocol.
