Abstract
A method and apparatus for the transmission of multiple control characters of the same type to a receiver to improve the retention of transmitter to receiver synchronization in a noisy environment having receiver code that is less complex and does not require an increase in the bandwidth of the system since the control codes are already utilized to initiate other functions. Detection of any of the control characters of the same type by the receiver allows the receiver to maintain proper synchronization. The receiver will detect these control signals and anticipate the occurrence of an event within a predetermined time period.
