BSC: Binary Synchronous Communication

Binary Synchronous Communication (BSC), also known as bisync, is an old IBM protocol that was originally designed for batch transmissions between the IBM S/360 mainframe family and IBM 2780 and 3780 terminals. BISYNC establishes rules for transmitting binary-coded data between a terminal and a host computer's BISYNC port. While BISYNC is a half-duplex protocol, it will synchronize in both directions on a full-duplex channel. BISYNC supports both point-to-point (over leased or dial-up lines) and multipoint transmissions. BISYNC was replaced by SDLC (Synchronous Data Link Control).
