41 Aironet 4500/4800 and Cisco 340/350 series wireless network driver
43 .Cd "an* at pcmcia? function ?"
44 .Cd "an* at pci? dev ? function ?"
49 driver provides support for Aironet Communications 4500/4800
50 and Cisco Aironet 340/350 series
51 wireless network adapters.
52 This includes the ISA, PCI and PCMCIA
54 The 4500 series adapters operate at 1 and 2Mbps while
55 the 4800 series and 340/350 series can operate at 1, 2, 5.5 and 11Mbps.
57 and PCMCIA devices are all based on the same core PCMCIA modules
58 and all have the same programming interface, however unlike the
59 Lucent WaveLAN/IEEE cards, the ISA and PCI cards appear to the
60 host as normal ISA and PCI devices and do not require any PCMCIA
63 The PCMCIA Aironet cards require PCMCIA support.
64 ISA cards can either be configured to use ISA Plug and Play
65 or to use a particular I/O address and IRQ
66 by properly setting the DIP switches on the board.
67 (The default switch setting is for plug and play.)
70 driver has Plug and Play support and will work in either configuration,
71 however when using a hard-wired I/O address and IRQ, the driver
72 configuration and the NIC's switch settings must agree.
74 require no switch settings of any kind and will be automatically
77 All host/device interaction with the Aironet cards is via programmed I/O.
78 The Aironet devices support 802.11 and 802.3 frames, power management,
79 BSS (infrastructure) and IBSS (ad-hoc) operation modes.
82 driver encapsulates all IP and ARP traffic as 802.11 frames, however
83 it can receive either 802.11 or 802.3 frames.
84 Transmit speed is selectable between 1Mbps, 2Mbps, 5.5Mbps, 11Mbps, or
86 (the NIC automatically chooses the best speed).
90 driver configures the Aironet card to join an access point with an SSID
92 For ad-hoc mode, in which
93 stations can communicate among each other without the aid of an access
94 point, the driver must be set using
