Abstract
A pseudo device driver is provided for use by an operation system in a virtual desktop computing environment. The driver has two ports, a master port that is opened by the driver application and a slave port accessed by a program. The two ports provide the functionality necessary for supporting the remote device on the terminal. When a program accesses a device coupled to the terminal, the program opens the pseudo device driver's slave port and proceeds as if the device were coupled to a local bus.
