Description:
Writing the character sequence '*' followed by a newline to
this file will delete all of the current pairings on the
device. Other character sequences are reserved. This file is
write only.

Description:
Reading from this file reports the mode status of the
remote as indicated by the LED lights on the device. If no
reports have been received from the paired device, reading
from this file will report '-1'. The mode is read-only
and cannot be set through the driver.
