cnwctl

CNWCTL(8)						    BSD System Manager's Manual 						 CNWCTL(8)

NAME

     cnwctl -- display statistics and control Netwave AirSurfer PC Cards

SYNOPSIS

     cnwctl [-d domain] [-i interface] [-k scramble-key] [-sS [rate]]

DESCRIPTION

     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 seconds.  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 statistics will be displayed.	These statistics are more detailed and include:

	     domain  The domain this card is part of.

	     rx      Number of packets received.

	     rxoverflow
		     Number of overflows detected.

	     rxoverrun
		     Number of overruns detected.

	     rxcrcerror
		     Number of CRC errors detected.  Random noise can cause these errors.

	     rxframe
		     Number of framing errors detected.

	     rxerrors
		     Number of generic errors detected.

	     rxavail
		     Number of times a packet was available.

	     tx      Number of packets requested to be sent.

	     txokay  Number of packets sent.

	     txabort
		     Number of packets aborted (not sent within 9 tries).

	     txlostcd
		     Number of times carrier detect was lost.

	     txerrors
		     Number of generic transmit errors detected.

	     txretries
		     Total number of retries.

	     Nx 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 access point.

	     spu     Unknown meaning.

	     link quality (lq)
		     Probably indicated the quality of the link to the access point.

	     hhc     Unknown meaning.

	     mhs     Unknown meaning.

	     revision
		     The revision numbers of the card.

	     id      The ID of the card.
