Name
====
LIRC_GET_REC_MODE - Get supported receive modes.
Synopsis
========
.. cpp:function:: int ioctl( int fd, int request, __u32 rx_modes)
Arguments

``fd``
File descriptor returned by open().
``request``
LIRC_GET_REC_MODE
``rx_modes``
Bitmask with the supported transmit modes.

=======================
.. _lirc-mode-mode2:
``LIRC_MODE_MODE2``
The driver returns a sequence of pulse and space codes to userspace.
.. _lirc-mode-lirccode:
``LIRC_MODE_LIRCCODE``
The IR signal is decoded internally by the receiver. The LIRC interface
returns the scancode as an integer value. This is the usual mode used
by several TV media cards.
