hardware flow control: out of band flow control defined in EIA RS-232-D that provides bidirectional flow control using the Request to Send (RTS) and Clear to Send (CTS) signals. The DTE (typically a computer) asserts RTS when it is able to accept input, and the DCE (typically a modem) asserts CTS when it is able to accept input.

High-Level Data Link Control. a bit-oriented framing and addresing scheme defined in ISO 3309 that is used as the basis for most modern synchronous wide-area data communications protocols, including PPP, X.25, SNA, OSI, and Frame Relay.
High density lipoprotein cholesterol. The fraction of plasma lipoprotein cholesterol component with most density (relative weight). It is thought to affect blood cholesterol levels by removing it from plasma and tissues and carrying it back to the liver for excretion after being acted on by bile. High levels of HDLC are considered to place an individual at a lower risk for coronary heart disease (atherosclerosis). Low levels of HDLC are associated with an increased risk for the disease. The density may be established by ultracentrifugation or electrophoresis.
An ISO standard set of protocols for carrying data over a link with error and flow control. Similar to IBM's SDLC, versions of HDLC are under development for multipoint lines. The ITU-TS later adapted HDLC for its Link Access Protocol used for X.25 networks. It is a bit-oriented data link control procedure under which all data transfer takes place in frames. Each frame ends with a frame check sequence for error detection. There is a control field at the start of each frame that allows error detection, and data link setup and data link termination. HDLC is, in fact, a misnomer, as it is not a high level protocol.
HDLC High-level Data Link Control
High-level Data Link Control is a group of protocols for transmitting [synchronous] data Packets between Point-to-Point nodes. Data is organized into a frame in HDLC. HDLC protocol resides with Layer 2 of the OSI model, the data link layer.

A bit-oriented data link protocol developed by the International Organization for Standardization (ISO). One of the most commonly used protocols in the data link layer (Layer 2) of the ISO's Open Systems Interconnection (OSI) reference platform, HDLC adds data link control information to a transmitted frame of data. Variations of HDLC are used in X.25 and frame relay networks. See OSI, frame relay and X.25.
