.. _FE_DISHNETWORK_SEND_LEGACY_CMD:
******************************
FE_DISHNETWORK_SEND_LEGACY_CMD
******************************
Name
====
FE_DISHNETWORK_SEND_LEGACY_CMD
Synopsis
========
.. c:function:: int ioctl(int fd, FE_DISHNETWORK_SEND_LEGACY_CMD, unsigned long cmd)
:name: FE_DISHNETWORK_SEND_LEGACY_CMD
Arguments
=========
``fd``
File descriptor returned by :c:func:`open() <dvb-fe-open>`.
``cmd``
Sends the specified raw cmd to the dish via DISEqC.
Description
===========
.. warning::
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.
Return Value
============
On success 0 is returned, on error -1 and the ``errno`` variable is set
appropriately. The generic error codes are described at the
:ref:`Generic Error Codes <gen-errors>` chapter.
