Abstract: A system for receiving queries from data entry means at a plurality of remote stations and for sending replies from a central station having data storage and data processing means to the appropriate remote station to be displayed on a data presentation means such as a cathode ray tube. The queries at the remote stations are interrogated by circuitry at an intermediate station. A recirculating memory means is provided at the intermediate station for assembling the query messages. A complete query is transmitted from the intermediate station to the central station where a reply message corresponding to the query is developed. The reply is transmitted back to the intermediate station and stored in a recirculating memory. The reply message is periodically sent as a succession of signals to the appropriate remote station to control the display on the data presentation means. Periodically, the central station interrogates all queries stored at the intermediate station, including those for which replies have previously been generated, and generates new replies in response to these queries. The information display at the remote station is in this manner maintained current.
