All host/device interaction is via programmed I/O with the Hermes. The Hermes supports 802.11 and 802.3 frames, power management, BSS, WDS and ad-hoc operation modes. Cards based on the Intersil PRISM-II and PRISM-2.5 chips provide similar functionality. In addition to the features supported by the Hermes controller, the PRISM-II and PRISM-2.5 support a host-based access point mode which allows a card to act as a normal access point (with some assistance from the .Nm driver). The Hermes does not contain this functionality. .Pp The .Nm driver encapsulates all IP and ARP traffic as 802.11 frames, however it can receive either 802.11 or 802.3 frames. Transmit speed is selectable between 1Mbps fixed, 2Mbps fixed, 2Mbps with auto fallback, 6Mbps, 8Mbps, or 11Mbps depending on your hardware (see above). The Lucent WaveLAN/IEEE Silver and Gold cards as well as the Intersil cards have support for WEP encryption. The WaveLAN Gold and newer Intersil cards support 104bit keys, the others only accept 40bit keys. The Lucent Bronze cards do not support WEP. To enable encryption, use the .Xr wicontrol 8 utility to set your keys. .Pp By default, the .Nm driver configures the card for BSS operation (aka infrastructure mode). This mode requires the use of an access point (base station). .Pp The .Nm driver also supports an ad-hoc (point-to-point) mode where the nwid is ignored and stations can communicate amongst themselves without the aid of an access point. Note that there are two possible ad-hoc modes. One mode, referred to as .Dq ad-hoc demo mode , predates the IEEE 802.11 specification and so may not interoperate with cards from other vendors. The standardized ad-hoc mode, also know as IBSS mode, is not supported by cards with very old firmware revisions. .Pp Cards based on the Intersil PRISM-II and PRISM-2.5 chips also have a host-based access point mode which allows the card to act as an access point (base station). .Pp For more information on configuring this device, see .Xr ifconfig 8 . .Pp Cards supported by the .Nm driver come in a variety of packages, though the most common are of the PCMCIA type. In many cases, the PCI version of a wireless card is simply a PCMCIA card bundled with a PCI adapter. The PCI adapters come in two flavors: true PCMCIA bridges and dumb PCMCIA bridges. A true PCMCIA bridge (such as those sold by Lucent) will attach as a real PCMCIA controller. The wireless card will then attach to the PCMCIA bus. Wireless cards in PCMCIA slots may be inserted and ejected on the fly. .br A dumb bridge, on the other hand, does not show up as a true PCMCIA bus. The wireless card will simply appear to the host as a normal PCI device and will not require any PCMCIA support. Cards in this type of adapter should only be removed when the machine is powered down. .Pp The following cards are among those supported to by .Nm driver: .Pp .in +\n(dIu .TS tab (:) ; l l l _ _ _ l l l .
