Abstract
A system for defining and controlling data transmissions in a multiplexing system having a host controller in bi-directional communication with a plurality of remote stations or nodes. The system comprises a series of simple frame flags generally defined as varying periods of inactivity on the bi-directional transmission line. Only specified numbers of transmitted data digits constitute valid transmissions. An arrangement is provided which responds to the receipt of an incorrect number of received digits (an error condition) in a manner which is a function of the number of digits which are actually received.
