  15 .TH WAVELAN 4 1996-10-22 "Linux" "Linux Programmer's Manual"
  16 .SH NAME
  17 wavelan \- AT&T GIS WaveLAN ISA device driver
  18 .SH SYNOPSIS
  19 .BI "insmod wavelan_cs.o [io=" B,B.. "] [ irq=" I,I.. "] [name=" N,N.. ]
  20 .SH DESCRIPTION
  21 .I wavelan
  22 is the low-level device driver for the NCR / AT&T / Lucent
  23 .B WaveLAN ISA
  24 and Digital (DEC)
  25 .B RoamAbout DS
  26 wireless ethernet adapter.
  27 This driver is available as a module or
  28 might be compiled in the kernel.
  29 This driver supports multiple cards
  30 in both forms (up to 4) and allocates the next available ethernet
  31 device (eth0..eth#) for each card found, unless a device name is
  32 explicitly specified (see below).
  33 This device name will be reported
  34 in the kernel log file with the MAC address, NWID and frequency used
  35 by the card.
  36 .SS Parameters
  37 This section apply to the module form (parameters passed on the
  38 .BR insmod (8)
  39 command line).
  40 If the driver is included in the kernel, use the
  41 .I ether=IRQ,IO,NAME
  42 syntax on the kernel command line.
  43 .TP
  44 .B io
  45 Specify the list of base address where to search for wavelan cards
  46 (setting by dip switch on the card).
  47 If you don't specify any io
  48 address, the driver will scan 0x390 and 0x3E0 addresses, which might
  49 conflict with other hardware...
  50 .TP
  51 .B irq
  52 Set the list of irq that each wavelan card should use (the value is
  53 saved in permanent storage for future use).
  54 .TP
  55 .B name
  56 Set the list of name to be used for each wavelan cards device (name
  57 used by
  58 .BR ifconfig (8)).
  59 .SS Wireless extensions
  60 Use
  61 .BR iwconfig (8)
  62 to manipulate wireless extensions.
  63 .SS NWID (or domain)
  64 Set the network ID
  65 .RI [ 0
  66 to
  67 .IR FFFF ]
  68 or disable it
  69 .RI [ off ].
  70 As the NWID is stored in the card Permanent Storage Area, it will be
  71 reuse at any further invocation of the driver.
  72 .SS Frequency & channels
  73 For the 2.4GHz 2.00 Hardware, you are able to set the frequency by
  74 specifying one of the 10 defined channels
  75 .RI ( 2.412,
  76 .I 2.422, 2.425, 2.4305, 2.432, 2.442, 2.452, 2.460, 2.462
  77 or
  78 .IR 2.484 )
  79 or directly by its value.
  80 The frequency is changed immediately and
  81 permanently.
  82 Frequency availability depends on the regulations...
  83 .SS Statistics spy
  84 Set a list of MAC addresses in the driver (up to 8) and get the last
  85 quality of link for each of those (see
  86 .BR iwspy (8)).
  87 .SS /proc/net/wireless
  88 .I status
  89 is the status reported by the modem.
  90 .I Link quality
  91 reports the quality of the modulation on the air (direct sequence
  92 spread spectrum) [max = 16].
  93 .I Level
  94 and
  95 .I Noise
  96 refer to the signal level and noise level [max = 64].
  97 The
  98 .I crypt discarded packet
  99 and
 100 .I misc discarded packet
 101 counters are not implemented.
 102 .SS Private ioctl
 103 You may use
 104 .BR iwpriv (8)
 105 to manipulate private ioctls.
 106 .SS Quality and level threshold
 107 Enable you the define the quality and level threshold used by the
 108 modem (packet below that level are discarded).
 109 .SS Histogram
 110 This functionality makes it possible to set a number of
 111 signal level intervals and
 112 to count the number of packets received in each of those defined
 113 intervals.
 114 This distribution might be used to calculate the mean value
 115 and standard deviation of the signal level.
 116 .SS Specific notes
 117 This driver will fail to detect some
 118 .B non-NCR/ATT&T/Lucent
 119 Wavelan cards.
 120 If this happens for you, you must look in the source code on
 121 how to add your card to the detection routine.
 122 .PP
 123 Some of the mentioned features are optional.
 124 You may enable to disable
 125 them by changing flags in the driver header and recompile.
