A method of duplex data transmission using a send-and-wait protocol.

摘要

The invention provides a method of communicating data between a pair of transceivers in a full-duplex manner using a send-and-wait data handling protocol. The transceivers are connected by a pair of communication paths and each transceiver is adapted to simultaneously transmit data on one communication path and receive data on the other. Each transceiver generates primary and secondary messages and these are multiplexed by injecting the secondary messages into the primary message stream in such a way that the secondary messages are readily differentiated from the primary messages at the receiving transceiver.
