Communication device sharing on a local area network

摘要

The X.25 device driver allows an X.25 card to be shared by workstations on a local area network. The approach used for the X.25 device driver may be used for sharing other devices on a local area network as well. The device driver for the device to be shared is implemented as a file system so that the device's location is hidden from application programs. Because the device driver is a file system driver, applications may use standard system calls, rather than device specific calls, to access the device.
