This script shows how to have with dwun
If you are able to run multiple dialscripts at once (for example, with two modems), then dwun does not support this very well.
(With multiple modems, you will have to run multiple copies of dwun, each on a different port. Make sure you specify a different ``pidfile'', ``commandon'' and ``commandoff'' for each. You may also wish to use different authfiles for each.
You can either just tell the users to connect to a different provider by connecting to a different port, or play port forwarding tricks).
