Abstract: A system and method of receiving HDLC communications is disclosed. The system measures the pulse width of the incoming signal and converts each pulse into a series of bits, based on its pulse width. In this way, the reception of the HDLC communication is not dependent on any particular clock rate and is adaptable. The system takes advantages of the fact that the flag is a string of six consecutive bits that are all “1”. Thus, the longest positive pulse width may be used to determine the bit rate. This allows the system to operate over a very broad range of data rates.
