Data Terminal Control and Partial Retransmission by Mini-Computer

Described is the use of a mini-computer for the communication control procedures, error detection, and data buffering of one to four on-line data terminals. The interface hardware is general and minimal. The character synchronization and control logic is done by software. An error correction scheme of partial record retransmission is developed. The resulting thruput is compared to that of the Idle-RQ system.
