Abstract
A data processing system including a processor that issues communications commands on a first communications channel and a peripheral device that is connected to the first communications channel and to a second communications channel that operates asynchronously relative to the first communications channel. The peripheral device performs communications operations specified from the commands from the processor and further responds to communications over the second communications channel. The peripheral device includes a controller that provides a status word to the processor in response to the command issued to the peripheral device. The status word indicates the status condition of the peripheral device at the time when the peripheral device initiates the operation specified by the issued command.
