cnwctl —
display statistics and control Netwave AirSurfer PC Cards
  
    | cnwctl | [ -ddomain]

      [-kscramble-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 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 -soption. 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.
