41 driver provides support for the Aztech/PackardBell radio cards.
43 The Aztech/PackardBell cards are stereo FM tuners that allow tuning
44 in the 87.5-108.0 MHz range.
45 They are capable of reporting signal status (tuned/not tuned, stereo/mono
46 signal) and forcing audio output to mono.
48 The Aztech cards use only one I/O port.
49 The I/O port is set by the driver to the value specified in the configuration
51 The I/O port must be one of

66 driver was written by Vladimir Popov and Maxim Tsyplakov.
67 The man page was written by Vladimir Popov.
69 It is impossible to determine to which frequency the card is tuned.
70 Thus, the driver will report an internally stored value even if it is not
71 correct (changed by some program that uses direct port access).
