Abstract

In a communication controller wherein the transfer of data between communications lines and host central processing unit is controlled by a central control unit, through line scanning devices, the circuits of these line scanning devices are checked by having an odd parity bit which is added to each byte. This bit is computed through parity look-ahead circuits.
