isdnconfig - configure the Debian isdnutils package
isdnconfig is used to interactively enable any required ISDN daemons
and other programs; skeleton configuration files are installed. Those
configuration files need to be edited by hand before anything useful
will happen. Upon starting the isdnutils programs, the init.d script
will tell you if any files are not yet configured manually.
isdnconfig was written by Andreas Jellinghaus specifically for Debian
GNU/Linux and isdn4linux, and is now maintained by Paul Slootman
