35 | =========== |
36 | ||
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. | |
40 | ||
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>`__ | |
