The init-script can be configured in /etc/sysconfig/ifled.

For users with a ppp dialup connection to an ISP the init-script
provided with the program will not work. Here is an alternate method:

Directory /etc/ppp contains the files "ip-up" and "ip-down".
Add the line "/usr/sbin/ifled console "$1" -f -c nna" *before*
"/etc/sysconfig/network-scripts/ifup-post ifcfg-${LOGDEVICE}"
to "ip-up".

Add "killall ifled 2> /dev/null" to "ip-down".

When you connect to the internet, ifled will be started automatically.
When you disconnect ifled will die.
