- <http://www.conectiva.com.br/~acme/cycsyn-devel/> (with minor changes
- to make it compile with the current wanrouter include files; efforts
- are being made to use the original package available at
- <ftp://ftp.sangoma.com/>).
-
- Feel free to contact me or the cycsyn-devel mailing list at
- additional details, I hope to have documentation available as soon as
- possible. (Cyclades Brazil is writing the Documentation).
-
- The next questions will ask you about the protocols you want the
- driver to support (for now only X.25 is supported).
-
- If you have one or more of these cards, say Y to this option.
-
- To compile this driver as a module, choose M here: the
- module will be called cyclomx.

- Connect a Cyclom 2X card to an X.25 network.
-
- Enabling X.25 support will enlarge your kernel by about 11 kB.
