Abstract

In attaching a terminal, such as an IBM 8775 display to a loop a probl exists in ensuring correct synchronization between the operation of the terminal data link controller (DLC) and the loop. The solution described in this article takes advantage of the SDLC (Synchronous Data Loop Control) architecture, which allows the 0 of a previous flag byte to be used in the succeeding flag byte.
