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).
