  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.
