Abstract: A data communication system comprises a communications controller and a processor having fixed hardware which utilizes control characters stored in memory to detect the end of messages being received from a variety of terminal devices, to detect changes in message code sets and to perform a variety of other functions. This system can accommodate a wide variety of message code sets, message formats, bit rates and line disciplines without any modification of hardware in the controller and processor.
