.Nd Fujitsu Brightness, Pointer, and Hotkeys
.Sh SYNOPSIS
.Cd "fujbp* at acpi?"
.Cd "fujhk* at acpi?"
.Sh DESCRIPTION
Some Fujitsu laptops come with vendor-specific
.Tn ACPI
devices to manage the laptop hotkeys (such as the
.Sq Eco
button), and to control various built-in components (such as the display,
the touchpad and the speakers).
The
.Nm
drivers provide support, through these
.Tn ACPI
devices, for hotkeys, backlight on/off switch, brightness level control, and
pointer on/off switch.
.Pp
The following
.Xr sysctl 8
read/write variables are provided (when hardware support is available):
.Bl -tag -width hw.acpi.fujbp0.brightness -offset indent
.It Va hw.acpi.fujbp0.brightness
Brightness level (integer).
.It Va hw.acpi.fujbp0.pointer
Pointer switch state (boolean).
.It Va hw.acpi.fujhk0.backlight
Backlight switch state (boolean).
.El
.Pp
Please note, however, that future versions of the
.Nm
drivers may remove these
.Xr sysctl 8
variables without prior notice.

.Sh CAVEATS
Brightness level and backlight switch state should be controlled via
.Xr wsconsctl 8
instead of
.Xr sysctl 8 .
.Pp
The
.Xr sysctl 8
variable
.Va hw.acpi.fujbp0.pointer
should be replaced by a platform-independent userland control.

.Sh NAME
.Nm otus
.Nd Atheros USB IEEE 802.11a/g/n wireless network device
.Sh SYNOPSIS
.Cd "otus* at uhub? port ?"
.Sh DESCRIPTION
The
.Nm
driver supports USB 2.0 wireless network devices based on Atheros
Communications AR9001U chipset.
.Pp
The AR9001U chipset is made of an AR9170 MAC/Baseband
and an AR9101 (1T2R), AR9102 (2T2R) or AR9104 (dual-band 2T2R)
Radio.
.Pp
These are the modes the
.Nm
driver can operate in:
.Bl -tag -width "IBSS-masterXX"
.It BSS mode
Also known as
.Em infrastructure
mode, this is used when associating with an access point, through
which all traffic passes.
This mode is the default.
.It monitor mode
In this mode the driver is able to receive packets without
associating with an access point.
This disables the internal receive filter and enables the card to
capture packets from networks which it wouldn't normally have access to,
or to scan for access points.
.El
.Pp
The
.Nm
driver can be configured to use
Wired Equivalent Privacy (WEP) or
Wi-Fi Protected Access (WPA-PSK and WPA2-PSK).
WPA is the de facto encryption standard for wireless networks.
It is strongly recommended that WEP
not be used as the sole mechanism
to secure wireless communication,
due to serious weaknesses in it.
.Pp
The
.Nm
driver can be configured at runtime with
.Xr ifconfig 8
or on boot with
.Xr ifconfig.if 5 .
.Sh FILES
The driver needs at least version 1.0 of the following firmware files,
which are loaded when an interface is attached:
.Pp
.Bl -tag -width Ds -offset indent -compact
.It /libdata/firmware/if_otus/otus-init
.It /libdata/firmware/if_otus/otus-main
.El
.Pp
Although these firmware files are freely redistributable, their usage
is restricted.
.Sh HARDWARE
The following adapters should work:
.Pp
.Bl -tag -width Ds -offset indent -compact
.It Arcadyan WN7512
.\" .It AVM FRITZ!WLAN USB Stick N
.It CACE AirPcap \&Nx
.It D-Link DWA-130 rev \&D1
.It D-Link DWA-160 rev A1
.It D-Link DWA-160 rev A2
.It IO-Data WN-GDN/US2
.It NEC Aterm WL300NU-G
.It Netgear WNDA3100
.It Netgear WN111 v2
.It Planex GW-US300
.It TP-Link TL-WN821N
.It Ubiquiti SR71 USB
.It Unex DNUA-81
.It Z-Com UB81
.It Z-Com UB82
.It ZyXEL NWD-271N
.El
.Sh EXAMPLES
The following
.Xr ifconfig.if 5
example configures otus0 to join whatever network is available on boot,
using WEP key
.Dq 0x1deadbeef1 ,
channel 11, obtaining an IP address using DHCP:
.Bd -literal -offset indent
nwkey 0x1deadbeef1 chan 11
dhcp
.Ed
.Pp
Join an existing BSS network,
.Dq my_net :
.Bd -literal -offset indent
# ifconfig otus0 192.168.1.1 netmask 0xffffff00 nwid my_net
.Ed
.Pp
To use WPA, see
.Xr wpa_supplicant 8
and
.Xr wpa_supplicant.conf 5 .
.Sh DIAGNOSTICS
.Bl -diag
.It "otus%d: error %d, could not read firmware %s"
For some reason, the driver was unable to read the microcode file from the
filesystem.
The file might be missing or corrupted.
.It "otus%d: device timeout"
A frame dispatched to the hardware for transmission did not complete in time.
The driver will reset the hardware.
This should not happen.

.Sh HISTORY
The
.Nm
driver first appeared in
.Ox 4.6 .
It was ported to
.Nx
by Anon Ymous and first appeared in
.Nx 6.0 .
.Sh AUTHORS
The
.Nm
driver was written by
.An Damien Bergamini Aq damien@openbsd.org
based on source code licensed under the ISC released in 2008 by Atheros
Communications for Linux.
.Sh CAVEATS
The AVM FRITZ!WLAN USB Stick N adapter is currently not supported.
.Pp
The
.Nm
driver does not support any of the 802.11n capabilities offered by the
AR9001U chipset.
Additional work is required in
.Xr ieee80211 9
before those features can be supported.
.Pp
The
.Nm
driver also does not currently support EDCA as this is missing in the
.Nx
network stack.
The hooks for it are in the driver code.
