NAME    [Toc]    [Back]

     wlconfig -- read/write wavelan config parameters

SYNOPSIS    [Toc]    [Back]

     wlconfig ifname [param value ...]

DESCRIPTION    [Toc]    [Back]

     The wlconfig utility can be used to read and set parameters for the
     NCR/AT&T Wavelan radio LAN card.  Various parameters stored in the nonvolatile
 Parameter Storage Area (PSA) on the card can be modified with
     this program, replacing the DOS-based instconf.exe program.  It can also
     be used to interrogate the optional signal strength cache which may have
     been compiled into the driver.

     The ifname parameter specifies the wavelan interface name (eg.  wl0).  If
     no other arguments are supplied, the current contents of the PSA are
     interpreted and displayed.

     The param and value arguments can be used to change the value of several
     parameters.  Any number of param value pairs may be supplied.

	   param	    value

	   irq		    IRQ value (used at next reset), may be one of

	   mac		    Local MAC value (ethernet address).

	   macsel	    `soft' (as set by the `mac' parameter) or
			    `default' (as set at the factory).

	   nwid 	    The NWID is a 2-byte parameter passed to the
			    card's radio modem.  NWIDs allow multiple logically
 discrete networks to operate independently
			    whilst occupying the same airspace.  Packets with
			    a different NWID are simply ignored by the modem.
			    In the hardware, NWIDs are stored long-term in
			    non-volatile memory (called the PSA or programmable
 storage area), and are loaded by software
 into the radio modem when the driver is initialized.
  This sets the default NWID loaded at

	   currnwid	    This sets the current operating NWID (but does not
			    save it to the PSA).

	   cache	    The driver may maintain a per interface fixed size
			    cache of signal strength, silence, and quality
			    levels, which are indexed by sender MAC addresses.
			    Input packets are stored in the cache, and when
			    received, the values stored in the radio modem are
			    interrogated and stored.  There are also two
			    sysctl values (iponly and multicast only) which
			    can be used for filtering out some input packets.
			    By default, the cache mechanism stores only nonunicast
 IP packets, but this can be changed with
			    sysctl(8).	Each non-filtered input packet causes
			    a cache update, hence one can monitor the antennae
			    signal strength to a remote system.  There are
			    three commands that can be given as values: `raw',
			    which prints out the raw signal strength data as
			    found in the radio modem hardware value, `scale',
			    which scales the raw hardware values to 0..100%,
			    and `zero' which clears out the cache in case you
			    want to store new samples.

     Note that if the IRQ on the Wavelan card is incorrect, the interface will
     be configured, but will not function.  The wlconfig utility should then
     be used to reconfigure the card to a sensible value.

EXAMPLES    [Toc]    [Back]

     Set the NWID to 0x1234:

     # wlconfig wl0 nwid 0x1234

     Show the current settings:

     # wlconfig wl0
     Board type 	   : ISA
     Base address options  : 0x300, 0x390, 0x3c0, 0x3e0
     Waitstates 	   : 0
     Bus mode		   : ISA
     IRQ		   : 10
     Default MAC address   : 08:00:0e:20:3d:4b
     Soft MAC address	   : 00:00:00:00:00:00
     Current MAC address   : Default
     Adapter compatibility : PC-AT 2.4GHz
     Threshold preset	   : 1
     Call code required    : NO
     Subband		   : 2425MHz
     Quality threshold	   : 3
     Hardware version	   : 0 (Rel1/Rel2)
     Network ID enable	   : YES
     NWID		   : 0xdead
     Datalink security	   : NO
     Databus width	   : 16 (variable)
     Configuration state   : unconfigured
     CRC-16		   : 0x3c26
     CRC status 	   : OK

     Print a scaled version of the signal strength cache:

     # wlconfig wl0 cache scale

HISTORY    [Toc]    [Back]

     This implementation of the wlconfig utility is completely new, written
     for Hilink Internet by Michael Smith, and updated by Jim Binkley &c.
