Your /cdrom is probably not valid. You should try explicitly naming the
cdrom device and the mount point as a test. mount -t iso9660 /dev/cdrom
/wherever. And also run "ls -l /dev/cdrom" and see if this symbolic link
points at the real device (the *correct* real device).

If you just run wvdial at a prompt and not background it, it will appear
to just sit there once you are connected; the connection dies when you
kill the prompt program. So run it in the background instead:
wvdial whatever &
(notice ampersand '&')

Now if you still can't get in/out, it means you have not attached a
route to the device, preferably a default route. Try checking the output
of "route" both before and after the connection. Don't know kppp, can't
comment on it.
