---------------------------------------
This feature is marked EXPERIMENTAL because the implementation
directly accesses hardware registers and may not work as expected. USE
WITH CAUTION! To use this feature, you need to supply the
experimental=1 parameter when loading the module.
This feature shows the presence and current state of a WAN (Sierra
Wireless EV-DO) device. If WAN is installed, the following commands can
be used:
echo enable > /proc/acpi/ibm/wan
echo disable > /proc/acpi/ibm/wan
It was tested on a Lenovo Thinkpad X60. It should probably work on other
Thinkpad models which come with this module installed.
