High-Level Data Link Control (HDLC) | mbedded.ninja
Overview High-Level Data Link Control (HDLC) is a synchronous data-link layer protocol. It was developed by the International Organization for Standardization (ISO). It only describes the data-link layer (layer 2 in the OSI model), and therefore is not really considered an communication protocol in it's own right. It may be used by other communication protocols such as LVDS.
