ABSTRACT:
A data communication apparatus for sending communication protocol signals and data has a low speed modem and a high speed modem. The protocol signal can be communicated by the high speed modem, and data communication can be started by the high speed modem without communication of a protocol signal by the low speed modem after communication of the protocol signals by the high speed modem. Other aspects of the data communication apparatus include the performance of ECM communication, the detection and storage of a communication result of a defined type to enable modification of future operations based on the stored result and the provision of first and second communication modes using recommended and not recommended communication protocols. The data communication apparatus can also communicate the protocol signal as data of a type otherwise communicated.
