Example DVB-S2 tune:

let cmdseq = vec![
    DtvProperty::new(DTV_DELIVERY_SYSTEM, SYS_DVBS2),
    DtvProperty::new(DTV_FREQUENCY, (11044 - 9750) * 1000),
    DtvProperty::new(DTV_MODULATION, PSK_8),
    DtvProperty::new(DTV_VOLTAGE, SEC_VOLTAGE_13),
    DtvProperty::new(DTV_TONE, SEC_TONE_OFF),
    DtvProperty::new(DTV_INVERSION, INVERSION_AUTO),
    DtvProperty::new(DTV_SYMBOL_RATE, 27500 * 1000),
    DtvProperty::new(DTV_INNER_FEC, FEC_AUTO),
    DtvProperty::new(DTV_PILOT, PILOT_AUTO),
    DtvProperty::new(DTV_ROLLOFF, ROLLOFF_35),
    DtvProperty::new(DTV_TUNE, 0),
];

let fe = FeDevice::open_rw("/dev/dvb/adapter0/frontend0")?;
fe.set_properties(&cmdseq)?;

Frontend information:

let fe = FeDevice::open_rd("/dev/dvb/adapter0/frontend0")?;
println!("{}", &fe);

Frontend status:

let fe = FeDevice::open_rd("/dev/dvb/adapter0/frontend0")?;
let mut status = FeStatus::default();
status.read(&fe)?;
println!("{}", &status);
