.Sh DESCRIPTION
|
|
|
|
The
|
|
|
|
.Nm
|
|
|
|
driver provides multiple virtual terminals.
|
|
|
|
It resembles the SCO color console driver.
|
|
|
|
.Pp
|
|
|
|
The
|
|
|
|
.Nm
|
|
|
|
driver is implemented on top of the keyboard driver
|
|
|
|
.Pq Xr atkbd 4
|
|
|
|
and the video card driver
|
|
|
|
.Pq Xr vga 4
|
|
|
|
and so requires both of them to be configured in the system.
|
|
|
|
.Pp
|
2001-05-01 09:15:30 +00:00
|
|
|
There can be only one
|
1999-02-10 14:25:03 +00:00
|
|
|
.Nm
|
|
|
|
device defined in the system.
|
|
|
|
.Ss Virtual Terminals
|
|
|
|
The
|
|
|
|
.Nm
|
|
|
|
driver provides multiple virtual terminals which appear as if they were
|
|
|
|
separate terminals.
|
|
|
|
One virtual terminal is considered current and exclusively
|
|
|
|
occupies the screen and the keyboard; the other virtual terminals
|
|
|
|
are placed in the background.
|
|
|
|
.Pp
|
|
|
|
In order to use virtual terminals, they must be individually
|
|
|
|
marked ``on'' in
|
|
|
|
.Pa /etc/ttys
|
2001-05-01 09:15:30 +00:00
|
|
|
so that
|
1999-02-10 14:25:03 +00:00
|
|
|
.Xr getty 8
|
|
|
|
will recognize them to be active and run
|
2001-05-01 09:15:30 +00:00
|
|
|
.Xr login 1
|
2003-04-21 19:08:35 +00:00
|
|
|
to let the user log in to the system.
|
1999-08-22 19:09:19 +00:00
|
|
|
By default, only the first eight virtual terminals are activated in
|
1999-02-10 14:25:03 +00:00
|
|
|
.Pa /etc/ttys .
|
|
|
|
.Pp
|
|
|
|
You press the
|
2000-10-03 22:51:27 +00:00
|
|
|
.Dv Alt
|
2001-05-01 09:15:30 +00:00
|
|
|
key and a switch key to switch between
|
1999-02-10 14:25:03 +00:00
|
|
|
virtual terminals.
|
|
|
|
The following table summarizes the correspondence between the switch
|
|
|
|
key and the virtual terminal.

.Pp
|
|
|
|
You can also use the ``nscr'' key (usually the
|
2000-10-03 22:51:27 +00:00
|
|
|
.Dv PrintScreen
|
1999-02-10 14:25:03 +00:00
|
|
|
key on the AT Enhanced keyboard) to cycle available virtual terminals.
|
|
|
|
.Pp
|
|
|
|
The default number of available virtual terminals is 16.
|
2003-04-21 19:08:35 +00:00
|
|
|
This can be changed with the kernel configuration option
|
2000-10-03 22:51:27 +00:00
|
|
|
.Dv MAXCONS
|
1999-02-10 14:25:03 +00:00
|
|
|
(see below).
|
|
|
|
.Pp
|
|
|
|
Note that the X server usually requires a virtual terminal for display
|
2001-05-01 09:15:30 +00:00
|
|
|
purposes, so at least one terminal must be left unused by
|
1999-02-10 14:25:03 +00:00
|
|
|
.Xr getty 8
|
|
|
|
so that it can be used by the X server.

|
.Ss Key Definitions and Function Key Strings
|
|
|
|
The
|
|
|
|
.Nm
|
|
|
|
driver, in conjunction with the keyboard driver, allows the user
|
|
|
|
to change key definitions and function key strings.
|
|
|
|
The
|
|
|
|
.Xr kbdcontrol 1
|
|
|
|
command will load a key definition file (known as ``keymap'' file),
|
|
|
|
dump the current keymap, and assign a string to a function key.
|
|
|
|
See
|
|
|
|
.Xr keyboard 4
|
|
|
|
and
|
2000-09-13 09:16:57 +00:00
|
|
|
.Xr kbdmap 5
|
1999-02-10 14:25:03 +00:00
|
|
|
for the keymap file.
|
|
|
|
.Pp
|
|
|
|
You may want to set the
|
|
|
|
.Ar keymap
|
2001-05-01 09:15:30 +00:00
|
|
|
variable in
|
1999-07-05 10:03:05 +00:00
|
|
|
.Pa /etc/rc.conf.local
|
1999-02-10 14:25:03 +00:00
|
|
|
to the desired keymap file so that it will be automatically loaded
|
|
|
|
when the system starts up.
|
|
|
|
.Ss Software Font
|
2004-06-16 08:33:57 +00:00
|
|
|
For most modern video cards, e.g., VGA, the
|
1999-02-10 14:25:03 +00:00
|
|
|
.Nm
|
2001-05-01 09:15:30 +00:00
|
|
|
driver and the video card driver allow the user to change
|
1999-02-10 14:25:03 +00:00
|
|
|
the font used on the screen.
|
|
|
|
The
|
|
|
|
.Xr vidcontrol 1
|
2001-05-01 09:15:30 +00:00
|
|
|
command can be used to load a font file from
|
1999-02-10 14:25:03 +00:00
|
|
|
.Pa /usr/share/syscons/fonts .
|
|
|
|
.Pp
|
|
|
|
The font comes in various sizes: 8x8, 8x14 and 8x16.
|
2003-04-21 19:08:35 +00:00
|
|
|
The 8x16 font is typically used for the VGA card in the
|
|
|
|
80-column-by-25-line mode.
|
|
|
|
Other video modes may require different font sizes.
|
|
|
|
It is better to always load all three sizes of the same font.
|
1999-02-10 14:25:03 +00:00
|
|
|
.Pp
|
|
|
|
You may set
|
|
|
|
.Ar font8x8 ,
|
2001-05-01 09:15:30 +00:00
|
|
|
.Ar font8x14
|
1999-02-10 14:25:03 +00:00
|
|
|
and
|
|
|
|
.Ar font8x16
|
|
|
|
variables in
|
2003-04-21 19:08:35 +00:00
|
|
|
.Pa /etc/rc.conf
|
1999-02-10 14:25:03 +00:00
|
|
|
to the desired font files so that they will be automatically loaded
|
|
|
|
when the system starts up.
|
|
|
|
.Pp
|
2003-04-21 19:08:35 +00:00
|
|
|
Optionally you can specify a particular font file as the default.
|
1999-02-10 14:25:03 +00:00
|
|
|
See the
|
2000-10-03 22:51:27 +00:00
|
|
|
.Dv SC_DFLT_FONT
|
1999-02-10 14:25:03 +00:00
|
|
|
option below.
|
|
|
|
.Ss Screen Map
|
2003-04-21 19:08:35 +00:00
|
|
|
If your video card does not support software fonts, you may still be able
|
2003-04-25 21:02:15 +00:00
|
|
|
to achieve a similar effect by re-mapping the font built into your video card.
|
1999-02-10 14:25:03 +00:00
|
|
|
Use
|
|
|
|
.Xr vidcontrol 1
|
2003-04-21 19:08:35 +00:00
|
|
|
to load a screen map file which defines the mapping between character codes.
|
1999-02-10 14:25:03 +00:00
|
|
|
.Ss Mouse Support and Copy-and-Paste
|
|
|
|
You can use your mouse to copy text on the screen and paste it as if
|
2003-04-21 19:08:35 +00:00
|
|
|
it was typed by hand.
|
1999-02-10 14:25:03 +00:00
|
|
|
You must be running the mouse daemon
|
|
|
|
.Xr moused 8
|
|
|
|
and enable the mouse cursor in the virtual terminal via
|
|
|
|
.Xr vidcontrol 1 .
|
|
|
|
.Pp
|
2003-04-21 19:08:35 +00:00
|
|
|
Pressing mouse button 1 (usually the left button) will start selection.
|
|
|
|
Releasing button 1 will end the selection process.
|
2001-05-01 09:15:30 +00:00
|
|
|
The selected text will be marked by inverting foreground and
|
1999-02-10 14:25:03 +00:00
|
|
|
background colors.
|
2003-04-21 19:08:35 +00:00
|
|
|
You can press button 3 (usually the right button) to extend
|
1999-02-10 14:25:03 +00:00
|
|
|
the selected region.
|
|
|
|
The selected text is placed in the copy buffer and can be pasted
|
2003-04-21 19:08:35 +00:00
|
|
|
at the cursor position by pressing button 2 (usually the
|
1999-02-10 14:25:03 +00:00
|
|
|
middle button) as many times as you like.
|
1999-11-08 14:16:48 +00:00
|
|
|
.Pp
|
|
|
|
If your mouse has only two buttons, you may want to use the
|
2000-10-03 22:51:27 +00:00
|
|
|
.Dv SC_TWOBUTTON_MOUSE
|
1999-11-08 14:16:48 +00:00
|
|
|
option below to make the right button to paste the text.
|
|
|
|
Alternatively you can make the mouse daemon
|
2003-04-21 19:08:35 +00:00
|
|
|
emulate the middle button.
|
1999-11-08 14:16:48 +00:00

|
See the man page for

.Ss Back Scrolling
|
|
|
|
The

driver allows the user to browse the output which has ``scrolled off''
|
2003-04-21 19:08:35 +00:00

|
the top of the screen.

This option sets the number of virtual terminals to

The default value is 16.

2000-10-03 22:51:27 +00:00
|

.It Dv SC_ALT_MOUSE_IMAGE
|
1999-07-05 10:03:05 +00:00
|
|
|
This option selects the alternative way of displaying the mouse cursor
|
|
|
|
in the virtual terminal.
|
2003-04-21 19:08:35 +00:00
|
|
|
It may be expensive for some video cards to draw the arrow-shaped
|
|
|
|
cursor, and you may want to try this option.
|
1999-07-05 10:03:05 +00:00
|
|
|
However, the appearance of the alternative mouse cursor may not be
|
2000-10-03 22:51:27 +00:00
|
|
|
very appealing.
|
|
|
|
Note that if you use the

|
.Dv SC_NO_FONT_LOADING
|

|
|

By default, its value is

|
|
|
.Qq Li \ex20

\(em a space character.

This options instructs the driver to convert leading spaces into tabs
|
2001-10-01 13:20:05 +00:00
|
|
|
when copying data into cut buffer.
|
|
|
|
This might be useful to preserve

2002-01-21 12:09:13 +00:00
|
|
|
indentation when copying tab-indented text.

entering the kernel debugger (KDB) by pressing the key combination.
|
|
|
|
KDB will still be invoked when the kernel panics or hits a break point
|
1999-07-05 10:03:05 +00:00

|
|
|
|
The amount of data that is possible to insert from the cut buffer is limited
|
|
|
|
by the
|
|
|
|
.Brq Dv MAX_INPUT ,
|
|
|
|
a system limit on the number of bytes that may be stored in the terminal
|
|
|
|
input queue - usually 1024 bytes
