  High-level Data Link Control
  HDLC
  
     <networking> (HDLC) A general-purpose data link control
     protocol defined by ISO for use on both point-to-point and
     multipoint (multidrop) data links.  It supports
     full-duplex, transparent-mode operation.  It is used
     extensively in both multipoint and computer networks.
  
     Some manufacturers and other standards bodies still use their
     own acronyms, e.g. IBM's SDLC (Synchronous Data Link Control
     ), the forerunner of HDLC and ANSI's ADCCP
     (Advanced Data Communications Control Procedure).
