.Sh DESCRIPTION
The
.Nm
2005-07-12 12:45:03 +04:00
tool allows to create, delete and switch between virtual terminals
on display devices controlled by the wscons terminal framework if
the underlying display hardware driver supports multiple screens.
Further it controls the assignment of keyboards to displays.
The
.Ar index
2005-07-12 12:45:03 +04:00
argument specifies which virtual terminal is to be configured; the
allowed numbers are from 0 to an implementation-specified value
(currently 7, allowing for 8 virtual terminals on a display).
1999-05-15 18:45:06 +04:00
In keyboard configuration mode, it specifies the
2001-04-03 16:01:39 +04:00
.Xr wskbd 4
1999-05-15 18:45:06 +04:00
device to attach or detach.
2005-07-12 12:45:03 +04:00
Without further option arguments, a virtual terminal is created
with implementation specific properties and a default terminal
emulation variant selected at kernel compile time.
.Pp
The options are:
.Bl -tag -width xxxxxxxxx
.It Fl d
2005-07-12 12:45:03 +04:00
Delete the specified terminal.
A terminal opened by a program will not be deleted unless the
.Fl F
2005-07-12 12:45:03 +04:00
option is applied.
Terminals used by the operating system console or a graphics program
(X server) cannot be deleted.
With the
1999-05-15 18:45:06 +04:00
.Fl k
flag, the keyboard specified by
.Ar index
1999-07-29 22:24:09 +04:00
will be detached from the wscons display.
With the
.Fl m
flag, the multiplexor specified by
.Ar index
1999-07-29 22:24:09 +04:00
will be detached from the wscons display.
2005-07-12 12:45:03 +04:00
.It Fl e Ar emul
Specify the terminal emulation to use for the virtual terminal.
The set of available terminal emulations is determined at kernel
compile time.
See
.Xr wscons 4
for details.
.It Fl F
2005-07-12 12:45:03 +04:00
Force deleting of a terminal even if it is in use by a user space
program.
.It Fl f Ar ctldev
Specify the control device of the wscons display to operate on.
Default is
.Pa /dev/ttyEcfg .
1999-05-15 18:45:06 +04:00
.It Fl k
Do keyboard related operations instead of virtual screen configuration.
2005-07-12 12:45:03 +04:00
Without other flags, a keyboard will be attached to the display
device.
The
.Ar index
2005-07-12 12:45:03 +04:00
argument can be omitted, in this case the first free keyboard will
be used.
1999-07-29 22:24:09 +04:00
.It Fl m
2005-07-12 12:45:03 +04:00
Do multiplexor related operations instead of virtual screen
configuration.
Without other flags, a multiplexor will be attached to the display
device.
.It Fl s
Switch to the specified virtual terminal.
.It Fl g
Print the index of the current virtual terminal.
.It Fl t Ar type
2005-07-12 12:45:03 +04:00
Specify a screen type to use.
Screen types refer to display format, colour depth and other
low-level display properties.
Valid
.Ar type
arguments are defined by the underlying display device driver.
.El
1999-03-31 19:37:47 +04:00
.Pp
Typically, the
.Nm
utility will be invoked in system startup by the
.Pa /etc/rc.d/wscons
1999-03-31 19:37:47 +04:00
script, controlled by the
.Pa /etc/wscons.conf
configuration file.

.Sh EXAMPLES
.Dl wsconscfg -t 80x50 -e vt100 1
.Pp
2005-07-12 12:45:03 +04:00
Configure screen 1 (i.e., the second), it will get the type
.Ql 80x50
2005-07-12 12:45:03 +04:00
and use the VT100 terminal emulation.
(Note:
.Ql 80x50
1999-03-31 19:37:47 +04:00
is a screen type offered by the
.Xr vga 4
2005-07-12 12:45:03 +04:00
display driver.
In this particular case, an 8\(mu8-font must be loaded before to
make the screen useful.
See
2001-04-03 16:01:39 +04:00
.Xr wsfontload 8 . )
1999-05-15 18:45:06 +04:00
.Pp
.Dl wsconscfg -k
.Pp
Connect the first unconnected keyboard to the display.
.Pp
.Dl wsconscfg 3
.Pp
Create screen 3.
.Pp
.Dl wsconscfg -d 3
.Pp
Delete screen 3.
.Pp
2005-11-30 21:31:45 +03:00
.Dl wsconscfg -s 2
.Pp
Switch to screen 2.

.Sh BUGS
2005-07-12 12:45:03 +04:00
There should be an easy way to get a list of the screen types
available on a display, and of the emulations supported by the
kernel.
