.Sh NAME
.Nm wlconfig
.Nd read/write wavelan config parameters
.Sh SYNOPSIS
.Nm wlconfig 
.Ar ifname
.Op Ar param value ...
.Sh DESCRIPTION
The 
.Nm wlconfig 
command 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, which
obviates the need for the DOS-based
.Nm instconf.exe
program.
.Pp
The
.Ar ifname
parameter specifies the wavelan interface name (eg. 
.Pa wl0
).  If no other arguments are supplied, the current contents of the PSA
are interpreted and displayed.
.Pp
The
.Ar param
and 
.Ar value
arguments can be used to change the value of several of the parameters.
Any number of 
.Ar param value
pairs may be supplied.
.Bl -tag -width 15n -compat -offset indent
.It Va param
.Va value
.It irq
IRQ value (used at next reset), may be one of 3,4,5,6,10,11,12,15
.It mac
Local MAC value (ethernet address)
.It macsel
.Sq soft
(as set by the 
.Sq mac
parameter) or
.Sq default
(as set at the factory).
.It nwid
The NWID is a 2-byte parameter passed to the card's radio modem.
NWIDs allow multiple logically discrete networks to operate 
independantly whilse 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-volative 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 startup.
.It curnwid
This sets the current operating NWID (but does not save it to the
PSA).
.El
.Pp
Note that if the IRQ on the Wavelan card is incorrect, the interface
will be configured, but will not function.  The
.Nm wlconfig
program should then be used to reconfigure the card to a sensible
value.
.Sh EXAMPLES
Set the NWID to 0x1234 :
.Bd -literal -offset
# wlconfig wl0 nwid 0x1234

This implementation of the
.Nm wlconfig
command is completely new, written for Hilink Internet by Michael Smith.
