WebAn HDLC frame terminated by an "abort" is discarded by the HDLC receiver. An abort sequence is often followed by a series of 1's. The sequence of all 1's may be used to fill the gaps between frames (or alternatively a continuous series of flags may be transmitted). The all 1's sequence is known as the "idle" sequence, since the line becomes ... WebJan 7, 2015 · What does HDLC Abort(6) mean?
