Abstract
The invention provides a new process and apparatus for generating and selectively processing command requests issued over a bus. Command requests are generated by devices, each of which may be authorized or not authorized to cause the execution of the requested command. A unique identifier is provided for each device. The command requests are received and the identity of the device which issued the command request is determined. The command is then executed only if the unique identifier associated with the requesting device indicates that the device is authorized to cause the execution of the requested command.
