This fileset provides all the common files necessary for the operation of the data link controls.

This fileset provides files that are common between the IEEE (802.3) Ethernet and Standard Ethernet data link Controls.

This fileset provides full-duplex peer data transfer capabilities over an FDDI token-ring local area network, using the American National Standards Institute (ANSI) standard publication Fiber Distributed Data Interface - Token Ring Media Access Control and a superset of the Institute of Electrical and Electronic (IEEE) 802.2 logical link control protocol.

This fileset provides full-duplex peer data transfer capabilities over an Ethernet local area network, using the IEEE 802.3 CSMA/CD medium access control and a superset of the IEEE 802.2 logical link control protocol.

This fileset provides full-duplex peer data transfer capabilities over an Ethernet local area network, using the Ethernet Version 2 CSMA/CD medium access control and a superset of the IEEE 802.2 logical link control protocol.

This fileset provides a half-duplex access procedure for transparent and code-independent information interchange across data and teleprocessing links using the IBM Synchronous Data Link Control (SDLC) protocol.

This fileset provides a half-duplex access procedure for attachment to an X.25 packet-switching network. This data link control provides full support for the 1980 and 1984 version of the Consultative Committee on International Telegraphy and Telephone (CCITT) recommendations relevant to SNA-to-SNA connections. It supports point-to-point connections over an X.25 network between a pair of primary and secondary link stations.

This fileset provides full-duplex peer data transfer capabilities over a token-ring local area network, using the token-ring IEEE 802.5 medium access control and a superset of the IEEE 802.2 logical link control protocol.
