LIRC supports some modes of receiving and sending IR codes, as shown
on the following table.
+.. _lirc-mode-scancode:
+
+``LIRC_MODE_SCANCODE``
+
+ This mode is for both sending and receiving IR.
+
+ For transmitting (aka sending), create a ``struct lirc_scancode`` with
+ the desired scancode set in the ``scancode`` member, ``rc_type`` set
+ the IR protocol, and ``flags`` set to 0. Write this to the lirc device.
+
+ For receiving, you read ``struct lirc_scancode`` from the lirc device,
+ with ``scancode`` set to the received scancode in the IR protocol
+ ``rc_type``. The ``flags`` can have ``LIRC_SCANCODE_FLAG_TOGGLE`` set
+ if the toggle bit is set in protocols that support it (e.g. rc-5 and rc-6),
+ or ``LIRC_SCANCODE_FLAG_REPEAT`` for when a repeat is received for protocols
+ that support it (e.g. nec).
+
+ An ``enum rc_type`` in the :ref:`lirc_header` lists all the supported
+ IR protocols.
