19 :name: FE_DISEQC_SEND_BURST
26 File descriptor returned by :ref:`open() <frontend_f_open>`.
29 pointer to enum :ref:`fe_sec_mini_cmd <fe-sec-mini-cmd>`
35 This ioctl is used to set the generation of a 22kHz tone burst for mini
36 DiSEqC satellite selection for 2x1 switches. This call requires
37 read/write permissions.
39 It provides support for what's specified at
40 `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>`__
42 .. _fe-sec-mini-cmd-t:
49 .. flat-table:: enum fe_sec_mini_cmd
66 - Sends a mini-DiSEqC 22kHz '0' Tone Burst to select satellite-A
74 - Sends a mini-DiSEqC 22kHz '1' Data Burst to select satellite-B
80 On success 0 is returned, on error -1 and the ``errno`` variable is set
81 appropriately. The generic error codes are described at the
82 :ref:`Generic Error Codes <gen-errors>` chapter.
