  48 Description:    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.
  56 Values:         A numeric value.
  57                 0: RFKILL_STATE_SOFT_BLOCKED
