Abstract of the Disclosure An intelligent Input-Output Interface Control unit, des- ignated as a Line control Processor, which serves as a cont- rol channel for data-transfers between a main data process- ing system and a plurality of different peripheral devices. The Line Control Processor operates on a standard communica- tions and control discipline which makes the eccentricities of various peripheral units transparent to the Main System. Once initiated, the Line Control Processor can execute the data-transfer instructions within the overall system so as to relieve the central processor of involvement in these tasks. Message-block length data buffer memories are pro- vided within the Line Control Processor to permit data- transfers to and from the peripheral device, at the speed suitable to the peripheral device; and also to permit data- transfers between the Line Control Processor and the Main Memory at the high transfer speeds permitted by Main Memory. Each Line Control Processor is provided with capabilities of handling the idiosyncracies of the peripheral device to which it is dedicated while it provides status control information to the Main System and helps serve as a building block to facilitate expansion of peripheral devices within a data processing system on a simple economic basis. The message- block length buffer memories prevent access errors since complete record length message transfers can occur in any given data-transfer cycle, barring any emergency interrup- tions. -1-
