Abstract
A flow control circuit for a computer system including a first-in first-out buffer including a register for storing a value indicating the number of stages of the FIFO which are available to store data, circuitry for detecting whether an input/output device is able to process data more rapidly than the FIFO is emptied, and circuitry for providing an value greater than the number of stages actually available for storage in the FIFO if the input/output device is able to process data more rapidly than the FIFO is emptied.
