NAME

     rt - AIMS Lab Radiotrack FM radio device driver

SYNOPSIS

     rt0   at isa? port 0x30c
     rt1   at isa? port 0x20c
     rt*   at isapnp?
     radio* at rt?

DESCRIPTION

     The rt driver provides support for the AIMS Lab Radiotrack FM radio
     tuners and compatible - RadioReveal RA300 FM radio tuners and tuners at
     SoundForte RadioX SF16-FMI (Creative ViBRA16C PnP).

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

     The card is based on the LM7000 chip; see radio(4) for details.

     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 ei-
     ther 0x20c or 0x30c.

HISTORY

     The rt device driver appeared in OpenBSD 3.0.

AUTHORS

     The rt driver was written by Vladimir Popov <jumbo@narod.ru> and
     Maxim Tsyplakov <tm@oganer.net>. The man page was written by
     Vladimir Popov <jumbo@narod.ru>.

BUGS

     Support for the SF16-FMI cards is rather ugly, the driver can not deter-
     mine signal state and force audio output to mono.

     It is impossible to determine which frequency the card is tuned to. Thus,
     the driver will report an internally stored value even if it is not
     correct (e.g. tuning was done through the direct I/O access).
