-<para>This ioctl is used to set the generation of the continuous 22kHz tone.
-    This call requires read/write permissions.</para>
-<para>Usually, satellite antenna subsystems require that the digital TV
-    device to send a 22kHz tone in order to select between high/low band on
-    some dual-band LNBf. It is also used to send signals to DiSEqC equipment,
-    but this is done using the DiSEqC ioctls.</para>
-<para>NOTE: if more than one device is connected to the same antenna,
-    setting a tone may interfere on other devices, as they may lose
-    the capability of selecting the band. So, it is recommended that
-    applications would change to SEC_TONE_OFF when the device is not used.</para>
