61 driver provides multiple virtual terminals.
62 It resembles the SCO color console driver.
66 driver is implemented on top of the keyboard driver
68 and the video card driver
70 and so requires both of them to be configured in the system.
74 device defined in the system.
78 driver provides multiple virtual terminals which appear as if they were
80 One virtual terminal is considered current and exclusively
81 occupies the screen and the keyboard; the other virtual terminals
82 are placed in the background.
84 In order to use virtual terminals, they must be individually
89 will recognize them to be active and run
91 to let the user to login to the system.
92 By default, only the first eight virtual terminals are activated in
97 key and a switch key to switch between
99 The following table summarizes the correspondence between the switch
100 key and the virtual terminal.

110 You can also use the ``nscr'' key (usually the
112 key on the AT Enhanced keyboard) to cycle available virtual terminals.
114 The default number of available virtual terminals is 16.
115 This can be changed by the kernel configuration option
119 Note that the X server usually requires a virtual terminal for display
120 purposes, so at least one terminal must be left unused by
122 so that it can be used by the X server.
123 .Ss Key Definitions and Function Key Strings
126 driver, in conjunction with the keyboard driver, allows the user
127 to change key definitions and function key strings.
130 command will load a key definition file (known as ``keymap'' file),
131 dump the current keymap, and assign a string to a function key.
138 You may want to set the
141 .Pa /etc/rc.conf.local
142 to the desired keymap file so that it will be automatically loaded
143 when the system starts up.
145 For most modern video cards, e.g. VGA, the
147 driver and the video card driver allow the user to change
148 the font used on the screen.
151 command can be used to load a font file from
152 .Pa /usr/share/syscons/fonts .
154 The font comes in various sizes: 8x8, 8x14 and 8x16.
155 The 8x16 font is typically used for the VGA card in the 80-column-
157 Other video modes may require different size of font.
158 It is better to always load these three sizes of the same font.
166 .Pa /etc/rc.conf.local
167 to the desired font files so that they will be automatically loaded
168 when the system starts up.
170 Optionally you can make a particular font file as the default font.
175 If your video card does not support software font, you may still be able
176 to have similar effect by re-mapping font hard-wired in the video card.
179 to load a screen map file which defines mapping between character codes.
180 .Ss Mouse Support and Copy-and-Paste
181 You can use your mouse to copy text on the screen and paste it as if
183 You must be running the mouse daemon
185 and enable the mouse cursor in the virtual terminal via
188 Pressing the mouse button 1 (usually the left button) will start selection.
189 Releasing the button 1 will end the selection process.
190 The selected text will be marked by inverting foreground and
192 You can press the button 3 (usually the right button) to extend
194 The selected text is placed in the copy buffer and can be pasted
195 at the cursor position by your pressing the button 2 (usually the
196 middle button) as many times as you like.
198 If your mouse has only two buttons, you may want to use the
199 .Em SC_TWOBUTTON_MOUSE
200 option below to make the right button to paste the text.
201 Alternatively you can make the mouse daemon
202 to emulate the middle button.
209 driver allows the user to browse the output which has ``scrolled off''
210 from the top of the screen.
212 Press the ``slock'' key (usually
216 keys on many AT Enhanced keyboards) and the terminal is
217 in the ``back scrolling'' mode.
218 It is indicated by the
225 keys to scroll buffered terminal output.
226 Press the ``slock'' key again to get back to the normal terminal mode.
228 The size of the back-scroll buffer can be set by the
234 driver can be made to put up the screen saver if the current
235 virtual terminal is idle, that is, the user is not typing
236 on the keyboard nor moving mouse.
242 .Sh DRIVER CONFIGURATION
243 .Ss Kernel Configuration Options
244 The following kernel configuration options control the
247 .Bl -tag -width MOUSE
249 This option sets the number of virtual terminals to
251 The default value is 16.
252 .It Em SC_ALT_MOUSE_IMAGE
253 This option selects the alternative way of displaying the mouse cursor
254 in the virtual terminal.
255 It may be vastly costly for some video cards to draw the arrow-shaped
256 cursor and you may want to try this option.
257 However, the appearance of the alternative mouse cursor may not be
259 .It Em SC_DISABLE_DDBKEY
260 This option disables the ``debug'' key (by default, it is
265 It will prevent the user from
266 entering the kernel debugger DDB by pressing the key combination.
267 DDB will still be invoked when the kernel panics or hits a break point
268 if it is included in the kernel.
269 .It Em SC_DISABLE_REBOOT
270 This option disables the ``reboot'' key (by default, it is
272 ), so that the casual user may not accidentally reboot the system.
273 .It Em SC_HISTORY_SIZE=N
274 Sets the size of back scroll buffer to
277 The default value is 100.
278 .It Em SC_MOUSE_CHAR=C
280 .Em SC_ALT_MOUSE_IMAGE
281 option above is specified, the
284 driver reserves four consecutive character codes in order to display the
285 mouse cursor in the virtual terminals in some systems.
286 This option specifies the first character code to
288 to be used for this purpose.
289 The default value is 0xd0.
290 A good candidate is 0x03.
292 Adds support for pixel (raster) mode console.
293 This mode is useful on some laptop computers, but less so on
294 most other systems, and it adds substantial amount of code to syscons.
295 If the this option is NOT defined, you can reduce the kernel size a lot.
299 .It Em SC_TWOBUTTON_MOUSE
300 If you have a two button mouse, you may want to add this option
301 to use the right button of the mouse to paste text.
303 .Sx Mouse Support and Copy-and-Paste
305 .It Em SC_NORM_ATTR=\&"_attribute_\&"

307 .It Em SC_KERNEL_CONS_ATTR=\&"_attribute_\&"
308 .It Em SC_KERNEL_CONS_REV_ATTR=\&"_attribute_\&"
309 These options will set the default colors.
310 Available colors are defined in
311 .Pa /usr/include/machine/pc/display.h .
316 This option will specify the default font.
317 Available fonts are: iso, iso2, koi8-r, cp437, cp850, cp865 and cp866.
318 16-line, 14-line and 8-line font data will be compiled in.
319 Without this option, the
321 driver will use whatever font already loaded in the video card,
322 unless you explicitly load software font at startup.
328 The following options will remove some features from the
330 driver and save kernel memory.
331 .Bl -tag -width MOUSE
332 .It Em SC_NO_CUTPASTE
333 This option disables ``copy and paste'' operation in virtual
335 .It Em SC_NO_FONT_LOADING
338 driver can load software font on some video cards.
339 This option removes this feature.
341 This option disables back-scrolling in virtual terminals.

359 .Pq see Xr config 8 ,
360 or else in the User Configuration Menu at boot
363 .Bl -tag -width bit_0

365 .\"Uses the ``visual'' bell.

383 .It bit 7 (VESA800X600)
384 This option puts the video card in the VESA 800x600 dots, 16 color

387 is otherwise unsupported by the X server.

426 the last line is not necessary, and can be omitted.
428 Note that the keyboard controller driver
430 is required by the keyboard driver
433 The following lines will set the default colors.
434 The normal text will be green on black background.
435 The reversed text will be yellow on green background.
436 Note that you cannot put any white space inside the quoted string,
437 because of the current implementation of
440 .Dl "options SC_NORM_ATTR"=\&"(FG_GREEN|BG_BLACK)\&"
441 .Dl "options SC_NORM_REV_ATTR"=\&"(FG_YELLOW|BG_GREEN)\&"
