Abstract

A field-proven scheme for achieving reliable duplex transmission over a half-duplex communication line is presented, and to demonstrate the difficulty of the problem, another similar scheme, which is only slightly unreliable, is also presented. A flowchart for the reliable scheme and some interesting examples are given.
