@brief DVB ioctl wrapper for setting SEC voltage
@ingroup frontend
@param parms struct dvb_v5_fe_parms pointer to the opened device
@param on a value different than zero indicates to enable
voltage on a Satellite Equipment Control (SEC)
@param v18 if on != 0, a value different than zero means 18 Volts;
zero means 13 Volts.
If dvb_v5_fe_parms::lnb is set, this is controlled automatically.
