The minitel daemon keeps a settings file in /etc/minitel.cfg, which is loaded on start. This can be edited directly and the daemon restarted, or settings can be changed from the command line.
In addition, one can invoke to get large amounts of debug output, *rc minitel set_route <hostname> <local_modem> <remote_modem>* to add a static route, and *rc minitel del_route <hostname>* to delete a static route.
