DESCRIPTION    [Toc]    [Back]

     The raycontrol utility controls the operation of Raylink/Webgear wireless
     networking devices via the ray(4) driver.	Most of the parameters that
     can be changed relate to the IEEE 802.11 protocol which the card implements.
  This includes the station name, whether the station is operating
     in ad-hoc or infrastructure mode, and the network name of a service set
     to join - the BSS in ad-hoc mode or ESS if infrastructure mode is
     enabled.  The raycontrol utility can also be used to view the current
     settings of these parameters and to dump out the values of the card's
     statistics counters.

     The iface argument given to raycontrol should be the logical interface
     name associated with the Raylink/Webgear device (ray0, ray1, ...).

OPTIONS    [Toc]    [Back]

     The options are as follows:

     -i iface [-o]
		 Display the current settings of the specified Raylink/Webgear
		 interface.  This retrieves the current card settings from the
		 driver and prints them out.  The results from this command
		 are a snapshot of the card settings.  Using the additional -o
		 flag will cause raycontrol to print out the statistics counters
 instead of the card settings.

     -i iface -t tx rate
		 Set the transmit rate of the specified interface.  The NICs
		 support a maximum transmit rate of 2Mbps.  The following table
 shows the legal transmit rate settings and the corresponding
 transmit speeds:

		       TX rate	   NIC speed
		       1	   Very Low (0.5Mbps)
		       2	   Low (1Mbps)
		       3	   Medium (1.5Mbps)
		       4	   High (2Mbps)

		 The version 4 firmware may ignore this setting.  Note, that
		 the IEEE 802.11 standard only allows 1Mbps or 2Mbps operation,
 and that the generally accepted reading of the IEEE
		 802.11 standard is that 2Mbps is only allowed in infrastructure
 mode.

     -i iface -n network name
		 Set the name of the service set that this station wishes to
		 join.	The network name can be any text string up to 32 characters
 in length.  The default name is the string "NETWORK_NAME"
 which should allow the station to connect to the
		 default Webgear ad-hoc network.

     -i iface -p port type
		 Set the port type for a specified interface.  The legal values
 for port type are 0 (ad-hoc mode) and 1 (infrastructure
		 mode).  In ad-hoc mode, the station can communicate directly
		 with any other stations within direct radio range (provided
		 that they are also operating in ad-hoc mode).	In infrastructure
 mode, hosts must associate with a service set controlled
		 by an access point, that relays traffic between end stations.
		 The default setting is 0 (ad-hoc mode).

		 When in ad-hoc mode the station will create a BSS with the
		 network name specified by the -n option if it cannot find an
		 existing network of that name on the currently configured
		 hopset (see the -f option).

     -i iface -m mac address
		 Set the station address for the specified interface.  The mac
		 address is specified as a series of six hexadecimal values
		 separated by colons, e.g.: 00:60:1d:12:34:56.	This programs
		 the new address into the card and updates the interface as
		 well.

     -i iface -d max_data_length
		 Set the maximum transmit frame size for a specified interface.
	The max data length can be any number from 350 to 2304
		 or -1 to disable fragmentation.  The default is -1.

     -i iface -r RTS threshold
		 Set the RTS/CTS threshold for a given interface.  This controls
 the number of bytes used for the RTS/CTS handshake
		 boundary.  The RTS threshold can be any value between -1 and
		 2047.	The default is -1 (disable).

     -i iface -f hopset
		 Set the radio hopset of a given interface.  The hopset should
		 be specified as a country code as shown in the table below.
		 The hopset varies both the number of RF channels and their
		 frequencies and is dependent on radio regulations specified
		 by regional authorities.

		       Hopset ID     Country
		       1	     USA
		       2	     Europe
		       3	     Japan
		       4	     Korea
		       5	     Spain
		       6	     France
		       7	     Israel
		       8	     Australia
		       9	     Japan Test

		 Whilst the card can be programmed to work with any hopset it
		 makes sense to use the hopset for your own region to avoid
		 interference from and interfering with other users of the RF
		 spectrum (in places like France this is the military).

		 Note that all stations must be set to the same hopset in
		 order to communicate.

     -i iface -P 0|1
		 Enable or disable power management on a given interface.
		 Enabling power management uses an alternating sleep/wake protocol
 to help conserve power on mobile stations, at the cost
		 of some increased receive latency.  Power management is off
		 by default.

		 Note that power management requires the cooperation of an
		 access point in order to function; it is not functional in
		 ad-hoc mode.  Legal values for this parameter are 0 (off) and
		 1 (on).

     -i iface -S max_sleep_interval
		 Specify the sleep interval to use when power management is
		 enabled.  The max_sleep_interval is specified in milliseconds.
	The default is 100.

     -i iface -Z
		 Clear the signal strength cache maintained internally by the
		 ray(4) driver.

     -i iface -C
		 Display the cached signal strength information maintained by
		 the ray(4) driver.  The driver retains information about signal
 strength and noise level for packets received from different
 hosts.	For infrastructure networks the cache stores
		 the signal strength of the access point.

		 The driver also uses the cache to pick the best antenna when
		 transmitting.

HISTORY    [Toc]    [Back]

     The raycontrol utility first appeared in FreeBSD 4.0.

AUTHORS    [Toc]    [Back]

     The raycontrol utility was written by Duncan Barclay
     <dmlb@ragnet.demon.co.uk> and based on the wicontrol utility by Bill Paul
     <wpaul@ctr.columbia.edu>.

BUGS    [Toc]    [Back]

     The -m, -P, -S and -Z options aren't implemented yet.  No access point
     was available for testing against.

     Not tested with Version 5 firmware.

     Hopset changing may not work with version 4 firmware.

     The -W option is un-documented on purpose.
