35 | .. warning:: |
| 36 | This is a very obscure legacy command, used only at stv0299 | |
| 37 | driver. Should not be used on newer drivers. | |

38 | |
| 39 | It provides a non-standard method for selecting Diseqc voltage on the | |
| 40 | frontend, for Dish Network legacy switches. | |
| 41 | ||
| 42 | As support for this ioctl were added in 2004, this means that such | |
| 43 | dishes were already legacy in 2004. | |
