Method and system for application program visiting physical peripheral

The invention provides a method for application program visiting physical peripheral. The method includes simulating and generating device data of the physical peripheral to be visited by the application program, visiting the device data according to request information of the application visiting physical peripheral, and resending the device data returned during the visiting process back to the application program. The invention further provides a system for application program visiting physical peripheral. With the method and the system, dependency on the physical peripheral can be broke away during the application program visiting physical peripheral process, the method and the system have high operability, and can simulate any physical peripheral and physical peripheral states, so that the application program can acquire any needed physical peripheral information.
