Data communication system.

摘要

This invention relates to a pseudo-synchronized data communication system wherein a plurality of remote stations (12, 14), in response to a request from a primary terminal (16), will transmit requested data to the primary terminal and to a secondary terminal (18). The secondary terminal is operable to receive and process the data transmitted in synchronism with the requests from the primary, and without any synchronizing information between the primary and secondary terminals. This is accomplished with the provision of data processing means in the two terminals which have identical memory maps (40, 80) of the sequencing operation.
