1.1 gluk 45: .Sh DESCRIPTION
46: The
47: .Nm
48: command displays or sets various variables that affect the radio tuner
49: behavior. If a variable is present on the command line,
50: .Nm
51: prints the current value of this variable for the specified device.
52: By default,
53: .Nm
54: operates on the
55: .Pa /dev/radio
56: device.
57: .Pp
58: The options are as follows:
59: .Bl -tag -width Ds
60: .It Fl a
61: Print all device variables and their current values.
1.8 jaredy 62: .It Fl f Ar file
63: Specify an alternative radio tuner device.
64: .It Fl n
