-.Sh NAME
-.Nm rt
-.Nd AIMS Lab Radiotrack FM radio device
-.Sh SYNOPSIS
-.Cd "rt0   at isa? port 0x30c"
-.Cd "rt1   at isa? port 0x20c"
-.Cd "rt*   at isapnp?"
-.Cd "radio* at rt?"
-.Sh DESCRIPTION
-The
-.Nm
-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).
-.Pp
-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.
-.Pp
-The card is based on the LM7000 chip; see
-.Xr radio 4
-for details.
-.Pp
-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.

-.Sh HISTORY
-The
-.Nm
-device driver appeared in
-.Ox 3.0 .
-.Sh AUTHORS
-.An -nosplit
-The
-.Nm
-driver was written by
-.An Vladimir Popov Aq Mt jumbo@narod.ru
-and
-.An Maxim Tsyplakov Aq Mt tm@oganer.net .
-The man page was written by
-.An Vladimir Popov Aq Mt jumbo@narod.ru .
-.Sh BUGS
-Support for the SF16-FMI cards is rather ugly, the driver cannot
-determine signal state and force audio output to mono.
-.Pp
-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).
