Binary Synchronous Transmission
<protocol> (Bisynch) An IBM link protocol, developed in
the 1960 and popular in the 1970s and 1980s.
Binary Synchronous Transmission has been largely replaced in
IBM environments with SDLC. Bisync was developed for
batch communications between a System 360 computer and the
IBM 2780 and 3780 Remote Job Entry (RJE) terminals. It
supports RJE and on-line terminals in the CICS/VSE
environment. It operates with EBCDIC or ASCII character
sets. It requires that every message be acknowledged (ACK)
or negatively acknowledged (NACK) so it has high
transmission overhead. It is typically character oriented and
half-duplex, although some of the bisync protocol flavours
or dialects support binary transmission and full-duplex
operation.
