Abstract

A method is described in which a simple serial channel generates a hardware level Busy frame in response to correctly addressed, incoming connect frames from the time the channel internally enters stopped state until the first Idle sequence is recognized after the channel accepts a subsequent Start command. The Busy response, therefore, originates when the channel is in the process of reinstruction, and not when it is actually busy performing an operation.
