48Description: 	Current state of the transmitter.
49		This file was scheduled to be removed in 2014, but due to its
50		large number of users it will be sticking around for a bit
51		longer. Despite it being marked as stable, the newer "hard" and
52		"soft" interfaces should be preferred, since it is not possible
53		to express the 'soft and hard block' state of the rfkill driver
54		through this interface. There will likely be another attempt to
55		remove it in the future.
56Values: 	A numeric value.
57		0: RFKILL_STATE_SOFT_BLOCKED
58			transmitter is turned off by software
59		1: RFKILL_STATE_UNBLOCKED
60			transmitter is (potentially) active
61		2: RFKILL_STATE_HARD_BLOCKED
62			transmitter is forced off by something outside of
63			the driver's control.
