31.Sh NAME
32.Nm gtp
33.Nd Gemtek PCI FM radio device
34.Sh SYNOPSIS
35.Cd "gtp*   at pci? flags 0x00"
36.Cd "radio* at gtp?"
37.Sh DESCRIPTION
38The
39.Nm
40driver provides support for the Gemtek PCI and Guillemot MaxiRadio FM2000
41FM radio tuners.
42.Pp
43The Gemtek PCI cards are stereo FM tuners that can tune in the range
4487.5 \- 108.0 MHz, report signal status and stereo/mono on the current
45frequency, force audio output to mono, perform hardware signal search,
46and have an internal AFC.
47.Pp
48The card is based on the TEA5757 chip; see
49.Xr radio 4
50for details.
51.Pp
52The flags control the driver behavior.
53For example, with flags 0x01 the driver
54will assume that a TEA5759 chip is used.

60.Sh HISTORY
61The
62.Nm
63device driver appeared in
64.Ox 3.2
65and subsequently in
66.Nx 1.6
67wherein it replaced the
68.Xr mr 4
69driver.
70.Sh AUTHORS
71The
72.Nm
73driver and the man page was written by
74.An Vladimir Popov Aq Mt jumbo@narod.ru .
75.Sh BUGS
76It is impossible to determine which frequency the card is tuned to.
77Thus, the driver will report an internally stored value even if it is not
78correct (changed by some program that uses direct port access).
