| ``int ioctl(int fd, FE_DISHNETWORK_SEND_LEGACY_CMD, unsigned long cmd)`` |
| File descriptor returned by :c:func:`open()`. |
| Sends the specified raw cmd to the dish via DISEqC. |
| This is a very obscure legacy command, used only at stv0299 |
| driver. Should not be used on newer drivers. |
| It provides a non-standard method for selecting Diseqc voltage on the |
| frontend, for Dish Network legacy switches. |
| As support for this ioctl were added in 2004, this means that such |
| dishes were already legacy in 2004. |
| On success 0 is returned. |
| On error -1 is returned, and the ``errno`` variable is set |
| Generic error codes are described at the |
| :ref:`Generic Error Codes <gen-errors>` chapter. |
