    Hi,

    K means stop (kill?), S start. The numbers behind K and S are the
    priority, e.g. the order in which the services for this particular
    runlevel are stopped/started.

    Take a look at chkconfig(8) - this prog makes all the symlinks to the
    different /etc/rc.d/rc[0-6].d/ for you.
    Maybee a short look at init(8) gives you some further explanation about
    the different runlevels.

    But I am not really shure, if it is really nice, to put a modem daemon
    as a service there - maybee it would be better to link it somehow to the
    network scripts, so it gets started by the service 'network'. Anyhow, i
    realized my xdsl connection for now as system service with the following
    line in the xdsl script

    # chkconfig: 35 23 18

    and chkconfig.
    (xdsl is started in runlevels 3 and 5, start priority is 23, stop
    priority is 18).
