16 utility can be used to read and set parameters for the NCR/AT&T Wavelan
18 Various parameters stored in the non-volatile Parameter
19 Storage Area (PSA) on the card can be modified with this program, replacing
23 It can also be used to interrogate the optional signal
24 strength cache which may have been compiled into the driver.
28 parameter specifies the wavelan interface name (eg.
30 If no other arguments are supplied, the current contents of the PSA
31 are interpreted and displayed.
37 arguments can be used to change the value of several parameters.
40 pairs may be supplied.

45 IRQ value (used at next reset), may be one of 3,4,5,6,10,11,12,15.
47 Local MAC value (ethernet address).
54 (as set at the factory).
56 The NWID is a 2-byte parameter passed to the card's radio modem.
57 NWIDs allow multiple logically discrete networks to operate
58 independently whilst occupying the same airspace.
59 Packets with a different NWID are simply ignored by the modem.
60 In the hardware, NWIDs are stored long-term in non-volatile memory
61 (called the PSA or programmable storage area), and are loaded by
62 software into the radio modem when the driver is
64 This sets the default NWID loaded at startup.
66 This sets the current operating NWID (but does not save it to the
69 The driver may maintain a per interface fixed size cache of signal strength,
70 silence, and quality levels, which are indexed by sender MAC addresses.
71 Input packets are stored in the cache, and when received, the values
72 stored in the radio modem are interrogated and stored.
73 There are also two sysctl values (iponly and multicast only) which
74 can be used for filtering out some input packets.
76 cache mechanism stores only non-unicast IP packets, but this can
80 input packet causes a cache update, hence one can monitor
81 the antennae signal strength to a remote system.
82 There are three commands that can be given as values:
84 which prints out the raw signal strength data as found in the radio
87 which scales the raw hardware values to 0..100%, and
89 which clears out the cache in case you want to store new samples.
92 Note that if the IRQ on the Wavelan card is incorrect, the interface
93 will be configured, but will not function.
96 utility should then be used to reconfigure the card to a sensible
