Remote reset circuit
A remote reset circuit is described for remotely resetting a digital system, the remote reset circuit accepting a receiver data (RxD) signal and generating a reset signal upon receiving the correct RxD reset signal, the remote resetting circuit comprising in combination: adjustable one-shot means triggered by the RxD signal for providing a timed pulse output long enough in duration to permit the clocking in of a desired number of bits transmitted at a predetermined baud rate from the source of the RxD signal; timing means triggered by the timed pulse output of the adjustable one-shot means for providing a synchronous clock signal (Tsync); counting means triggered by the Tsync clock signal for counting the desired number of bits clocked in from the source of the RxD signal; means for presetting a desired reset pattern of bits; means for comparing the bits in the desired number of bits clocked in from the source of the RxD signal with the desired reset pattern of bits and for providing a match signal when the desired number of bits clocked in from the source of the RxD signal compares in pattern with the desired reset pattern of bits; and means for generating a signal to reset the digital system upon receipt of the match signal from the means for comparing.
