DESCRIPTION
     The rt driver provides support for the AIMS Lab Radiotrack FM radio tuners and compatible RadioReveal RA300 and SoundForte RadioX SF16-FMI FM
     radio tuners.

     The Radiotrack is a stereo FM tuner that allows to tune in the range 87.5 - 108.0 MHz, report signal status on the current frequency, and
     force audio output to mono.

     The Radiotrack cards take only one I/O port.  The I/O port is set by the driver to the value specified in the configuration file and must be
     either 0x20c or 0x30c.
