X.25 is a circuit based packet switching protocol defined by the C.C.I.T.T. (a standards body recognized by Telecommunications companies in most parts of the world). Implementations of X.25 and LAPB are currently being worked on, and recent 2.1.* kernels include the work in progress.
Jonathon Naylor email@example.com is leading the development. A mailing list has been established to discuss Linux X.25 related matters. If you'd like to subscribe, send a message to: firstname.lastname@example.org. Be sure to include the text "subscribe linux-x25" in the body of the message.
Early versions of the configuration tools may be obtained from Jonathon's ftp site at :ftp.cs.nott.ac.uk.
