ABSTRACT The present disclosure relates to a communications method for communicating data over a data channel that comprises two unidirectional communication lines. A protocol which is a set of predetermined control characters is used by the com- munications method and the protocol is used for transferring data between communicating devices. The communications method combines acknowledgments which are control characters of the protocol transmitted in between messages, piggy-backing which is the combining of control characters of the protocol and data messages, and hold-offs with long time outs which cause the devices to enter a standby idle mode waiting for a responsive control character of the protocol. The communications system and method combines these features so as to permit improved efficient flow control of data information between the com- municating devices.
