cnwctl -- display statistics and control Netwave AirSurfer PC Cards
cnwctl [-d domain] [-i interface] [-k scramble-key] [-sS [rate]]
The cnwctl utility is used to control Netwave AirSurfer PC Cards as well
as display statistics. The following options are available:
-d Set the domain of the card to domain. The domain must be between
0x000 and 0x1ff. The domains 0x000 through 0x0ff are for access
to an add-hoc network. The domains 0x100 through 0x1ff are for
access to a Netwave Access Point. The default domain is 0x000.
A card may only talk to the access point in its domain, or other
cards in its add-hoc domain.
-i Use interface as the interface rather than cnw0.
-k Set the scramble key to scramble-key. The scramble key must be
between 0x0000 and 0xffff. Both the source and the destination
must use the same scramble key in order to communicate.
-s Display statistics. When the optional argument rate (which must
be the last argument to the end of the command line) is specified
as a non-zero value, statistics will be displayed every rate sec-
onds. At the top of each ``page'' of statistics, column labels
will be displayed. The first row of statistics will be totals
since boot, subsequent lines are deltas from the previous row.
If rate is not specified, or is 0 (zero), a single page of sta-
tistics will be displayed. These statistics are more detailed
domain The domain this card is part of.
rx Number of packets received.
Number of overflows detected.
Number of overruns detected.
Number of CRC errors detected. Random noise can cause
Number of framing errors detected.
Number of generic errors detected.
Number of times a packet was available.
tx Number of packets requested to be sent.
txokay Number of packets sent.
Number of packets aborted (not sent within 9 tries).
Number of times carrier detect was lost.
Number of generic transmit errors detected.
Total number of retries.
Number of packets which were retried N times.
-S Display status read from the hardware. This option is only
available to the super user. The rate argument is used as with
the -s option. The following fields are displayed
link integrity field (lif)
A 0 value implies no links.
connection quality (cq)
Probably indicates the quality of the connection to the
spu Unknown meaning.
link quality (lq)
Probably indicated the quality of the link to the access
hhc Unknown meaning.
mhs Unknown meaning.
The revision numbers of the card.
id The ID of the card.
