Abstract
A method and apparatus for transmitting data between computers. By determining an optimum time for which a sending computer (10) must set a strobe pulse on a strobe line (54) in order for a receiving computer (30) to be able to read data transmitted, the sending computer can transmit data without the need to poll an acknowledge line (56). The optimum strobe pulse duration is determined by sending a copy of a known pattern of data from the sending computer to the receiving computer using different strobe pulse durations. The receiving computer examines the received pattern of data to determine if an error occurred during transmission. If an error occurred, the sending computer sets the acknowledge line. The optimum hold time is determined to be the shortest hold time for which the sending computer can set the strobe line and the receiving computer can receive the known pattern of data without error.
