32Description
33===========
34
35.. warning::
36   This is a very obscure legacy command, used only at stv0299
37   driver. Should not be used on newer drivers.
38
39It provides a non-standard method for selecting Diseqc voltage on the
40frontend, for Dish Network legacy switches.
41
42As support for this ioctl were added in 2004, this means that such
43dishes were already legacy in 2004.
