-.Sh DESCRIPTION
-The
-.Nm ncrcontrol
-command symbolically displays the contents of the ncr810/ncr825
-pci/scsi driver control structure.
-There are a number of output formats,
-depending on the options for the information presented.
-It may be used to set some values, too.
-
-.\"--------------------------------------------------------
-.\" ncrcontrol [-Mcore] [-Nsystem] [-u unit] [-v] [-v] -i
-.\"--------------------------------------------------------
-The first form of the command displays an overview of the
-connected targets. The
-.Fl v
-requests a verbose output.
-
-.\"--------------------------------------------------------
-.\" ncrcontrol [-N system] [-u unit] [-p wait]
-.\"--------------------------------------------------------
-Using the second form, with a
-.Ar wait
-interval specified,
-.Nm ncrcontrol
-will continuously display the information regarding data
-traffic on the selected scsi bus.
-
-.\"------------------------------------------------------------
-.\" ncrcontrol [-Nsystem] [-u unit] [-t target] -s name=value
-.\"------------------------------------------------------------
-The third form sets a configuration value for one or all
-targets of a selected scsi bus.
-It normally is not needed, if the device driver options are
-correctly set in kernel configuration.
-
-.\"------------------------------------------------------------
-.\" ncrcontrol [-M core] [-N system] [-u unit] [-t target] -w -d pattern
-.\"------------------------------------------------------------
-The forth form presents the content of the drivers control
-structure. By the
-.Ar pattern
-certain parts of the output can be enabled/disabled.
-It's only used to debug the driver.
-
-.\"------------------------------------------------------------
-.\" ncrcontrol [-N system] [-u unit] -w -k torture
-.\"------------------------------------------------------------
-With the last form certain driver problems can be forced.
-THIS MAY CRASH YOUR SYSTEM.
-It's only used to debug the driver.
-
-.\"
-.\"=====================================================================
-.\"
-.Pp
-The options have the following meaning:
-.Bl -tag -width flag
-.\"------------------------------------------------------------
-.\" -d pattern
-.\"------------------------------------------------------------
-.It Fl d
-Show the content of the drivers control structure.
-The
-.Ar pattern
-selects the fields, which are displayed. With
-.Fl d?
-you can get a list of valid flags.
-
-.\"------------------------------------------------------------
-.\" -i
-.\"------------------------------------------------------------
-.It Fl i
-Show the configuration state of the connected targets.
-With the
-.Fl v
-option you can request a more verbose information.
-
-.\"------------------------------------------------------------
-.\" -k torture
-.\"------------------------------------------------------------
-.It Fl k
-Force certain driver problems to check the error recovery
-functions. This option should only be used by the developers.
-With
-.Fl k?
-you can get a list of possible tortures.
-This option requires the
-.Fl w
-option to be set.
-
-.\"------------------------------------------------------------
-.\" -M core
-.\"------------------------------------------------------------
-.It Fl M
-Extract values associated with the name list from the specified core
-instead of the default
-.Pa /dev/kmem .
-.\"------------------------------------------------------------
-.\" -N system
-.\"------------------------------------------------------------
-.It Fl N
-Extract the name list from the specified system instead of the default
-.Pa /386bsd .
-
-.\"------------------------------------------------------------
-.\" -p wait
-.\"------------------------------------------------------------
-When
-.Nm ncrcontrol
-is invoked with a
-.Ar wait
-interval argument, it displays a running count of statistics related to
-the transfers on the selected scsi bus.
-
-This display consists of the number of transfers and number of transferred
-byted for the controller and for each connected target.

-.\"------------------------------------------------------------
-.\" -s field=value
-.\"------------------------------------------------------------
-.It Fl s
-Set a configuration value for one or more targets.
-One ore more targets can be selected by the
-.Fl t
-option. If no target is selected, then the field is set
-for all connect targets.

-
-.\"------------------------------------------------------------
-.\" -t target
-.\"------------------------------------------------------------
-.It Fl t
-Select the target for the
-.Fl s
-option. This option may be given more than one time.
-
-.\"------------------------------------------------------------
-.\" -u unit
-.\"------------------------------------------------------------
-.It Fl u
-Select the controller unit.
-If this option is not given, then controller 0 is assumed.
-Most systems have only one controller.
-
-.\"------------------------------------------------------------
-.\" -v
-.\"------------------------------------------------------------
-.It Fl v
-Enable verbose output for the

-.Sh HISTORY
-The

-command was hacked for
-.Bx 386
-and ported to version 1.1 of

-by Wolfgang Stanglmeier <wolf@dentaro.GUN.de>.
-It was ported to
-.Bx Net
-by Charles M. Hannum <mycroft@gnu.ai.mit.edu>
-and to version 2.0 of

-by Stefan Esser <se@zpr.Uni-Koeln.DE>.

-.\"=====================================================================
-.\"
-.Sh BUGS
-The
-.Nm ncrcontrol
-was hacked as a debugging tool for the ncr810 driver.
-It should be deleted sometimes.
-There should be a general tool to change device driver options
-on the fly.
-The statistical data should be gathered by the generic scsi driver.
