   9 The lircd userspace daemon reads raw IR data from the LIRC chardev. The
  10 exact format of the data depends on what modes a driver supports, and
  11 what mode has been selected. lircd obtains supported modes and sets the
  12 active mode via the ioctl interface, detailed at :ref:`lirc_ioctl`.
  13 The generally preferred mode is LIRC_MODE_MODE2, in which packets
  14 containing an int value describing an IR signal are read from the
  15 chardev.
