public interface CommandService
extends ControlService

The CommandService interface defines the CommandService concept. A CommandService is a logical representation of a message which is sent to a hardware Device, instructing it to do something. The execute methods are used in order to send the CommandService. An application may register interest by using the CommandListener interface, and be notified whenever the CommandService is sent.
