12 FE_DISEQC_SEND_BURST - Sends a 22KHz tone burst for 2x1 mini DiSEqC satellite selection.
18 .. cpp:function:: int ioctl( int fd, int request, enum fe_sec_mini_cmd *tone )
25 File descriptor returned by :ref:`open() <frontend_f_open>`.
31 pointer to enum :ref:`fe_sec_mini_cmd <fe-sec-mini-cmd>`
37 This ioctl is used to set the generation of a 22kHz tone burst for mini
38 DiSEqC satellite selection for 2x1 switches. This call requires
39 read/write permissions.
41 It provides support for what's specified at
42 `Digital Satellite Equipment Control (DiSEqC) - Simple "ToneBurst" Detection Circuit specification. <http://www.eutelsat.com/files/contributed/satellites/pdf/Diseqc/associated%20docs/simple_tone_burst_detec.pdf>`__
44 .. _fe-sec-mini-cmd-t:
51 .. flat-table:: enum fe_sec_mini_cmd
68 - Sends a mini-DiSEqC 22kHz '0' Tone Burst to select satellite-A
76 - Sends a mini-DiSEqC 22kHz '1' Data Burst to select satellite-B
82 On success 0 is returned, on error -1 and the ``errno`` variable is set
83 appropriately. The generic error codes are described at the
84 :ref:`Generic Error Codes <gen-errors>` chapter.
