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.

NAME
cnw -- Netwave AirSurfer wireless network driver SYNOPSIS
cnw* at pcmcia? function ? DESCRIPTION
The cnw interface provides access to a theoretical 1 Mb/s wireless Ethernet network based on the Netwave AirSurfer Wireless LAN (formerly known as the Xircom Netwave Wireless LAN). Note that the driver does not support newer devices such as the Netwave AirSurfer ``Plus'', or the BayStack 650/660. These devices are sup- ported by the awi(4) driver. Netwave devices are not compatible with IEEE 802.11 wireless networks. Also note that there are Netwave devices with different wireless fre- quency, depending on the radio band plan in each country. The card uses 36K of I/O memory mapped to the card. You may need to increase memory space available to the PCMCIA controller. See pcmcia(4) for details. In use, the cards appear to achieve up to a 420Kb/s transfer rate, though a transfer rate between 250Kb/s and 350Kb/s is typical. The card operates in the 2.4GHz frequency range and is subject to interference from microwaves, IEEE 802.11 wireless network devices, as well as earth. For example, it seems that IEEE 802.11 channel 14 conflicts with Netwave (US frequency). They interfere with each other if they are both operated in the same geographic region, causing weird packet loss. You may be able to avoid the interference with IEEE 802.11 devices, by changing the IEEE 802.11 channel. HARDWARE
Cards supported by the cnw driver include: Xircom CreditCard Netwave NetWave AirSurfer DIAGNOSTICS
cnw0: can't map memory Indicates that the driver was not able to allocate enough PCMCIA bus address space into which to map the device. See pcmcia(4) and increase memory available to the PCMCIA controller. SEE ALSO
