ABSTRACT:
A communication interface for interconnecting a computer with at least one other device has a link output circuit and a link input circuit. A link output on one device is connected to a link input on another device by a data line and a parallel strobe line. Data is transmitted on the data line in serial bit strings forming a succession of tokens of predetermined lengths. Signal transitions are provided on the parallel strobe line where no signal transition occurs on the data line. Each token includes a bit indicating the length of the token and a parity bit providing a check on bits in a preceding token.
