< 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 ).
