    摘要: The present invention provides a method and system for providing communication between a number of applications and a number of devices disposed in various relative locations in a data processing system through an interface that is capable of accessing only a single device at a prespecified relative location. The applications are concurrently executing within the data processing system. A device table is established for each of the applications, wherein each device table includes device parameter information and device address information for each of the devices in the data processing system. A particular device is specified for use with a selected application. Device parameter information and device address information for the prespecified relative location within the device table established for the application are overwritten with device parameter information and device address information for the particular device specified. Data is then directed from a particular application to a selected device utilizing the device parameter information and device address information stored within the device table for the particular application.
