.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.  It can also be used to interrogate the optional signal
strength cache which may have been compiled into the driver.
.Pp
[$BN,(B]
.It 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 non-unicast 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:
.Sq raw ,
which prints out the raw signal strength data as found in the radio
modem hardware value,
.Sq scale ,
which scales the raw hardware values to 0..100%, and
.Sq zero
which clears out the cache in case you want to store new samples.
