ABSTRACT:
A method and apparatus for improving the reliability of resynchronization in a serial frame based protocol communication system which can avoid resynchronization when line loss erroneously causes data to appear as a redundant unique code pattern. The synchronization is only initiated if two such unique code pattern bytes are received within a specified time separation.
