-.El
-
-.Ss Configuration
-The
-.Nm pcvt
-console driver is currently available for the Intel-based BSD operating
-systems
-.Tn NetBSD/i386
-(release 0.9 or higher),
-and
-.Tn FreeBSD
-(release 1.0-GAMMA or higher) .
-In order to get the appropriate system support, one of the options
-.Em PCVT_NETBSD ,
-or
-.Em PCVT_FREEBSD
-must be defined in the system's config file
-.Pq see Xr config 8 .
-In addition, for the
-.Tn FreeBSD
-and
-.Tn NetBSD
-operating systems, it is necessary to set this option to the operating
-system's version number.
-For
-.Tn FreeBSD
-this version number must be expressed as a 3-digit number.
-E.\& g., if you are running the 1.0 release
-.Pq which is actually version 1.0.2 ,
-you should define
-
-.Em PCVT_FREEBSD = 102
-
-For
-.Em NetBSD
-this version number must be expressed as 9 if you are running NetBSD 0.9
-and anything greater than 9 for NetBSD-current (pre 1.0). It is recommended
-to use (as with
-.Tn FreeBSD )
-100 for
-.Nx 1.0
-and 999 for
-.Tn NetBSD-current.
-E.g., if you are running the
-.Nx 1.0
-release, you should define
-
-.Em PCVT_NETBSD = 100
-
-The
-.Nm pcvt
-driver has been designed to be highly configurable in order to satisfy
-everyone's needs. The preferred way for those configurations is to
-provide appropriate
-.Em options
-lines within the config file, possibly overriding the built-in default
-values. Therefore it is possible to compile several distinct kernels
-with different driver behaviour on a single machine.
-
-The following list gives a short overview of the available configuration
-options. Refer to the file
-.Pa i386/isa/pcvt/pcvt_hdr.h
-in the kernel source tree for detailed documentation.
-
-Note: the following conventions apply to all the Boolean options.
-If an option is given with no value, a value of 1
-.Pq activated
-is substituted. If an option value is given as 0, this options is
-deactivated. Any other value is substituted by 1, too. If an option
-is omitted, a built-in default is assumed.
-
-.Bl -tag -width indent -compact
-
-.It Em PCVT_NSCREENS
-Defines the number of virtual screens.
-.br
-Default: 8
-
-.It Em PCVT_VT220KEYB
-If activated, a keyboard layout resembling a DEC VT200 (TM) is generated.
-If deactivated, a mixture between VT220 and HP is used. See the files
-.Pa Keyboard.VT
-and
-.Pa Keyboard.HP
-in the
-.Nm pcvt
-documentation directory for a full description.
-.br
-Default: off
-
-.It Em PCVT_SCREENSAVER
-Enables the builtin screensaver feature.
-.br
-Default: on
-
-.It Em PCVT_PRETTYSCRNS
-If enabled, a blinking-star screensaver is used. If disabled, the screen
-is simply blanked
-.Pq which might be useful for energy-saving monitors .
-.br
-Default: on
-
-.It Em PCVT_CTRL_ALT_DEL
-If enabled, the key combination
-.Aq Em Ctrl
-.Aq Em Alt
-.Aq Em Del
-invokes a CPU reset.
-.br
-Default: off
-
-.It Em PCVT_USEKBDSEC
-Do NOT override a security lock for the keyboard.
-.br
-Default: on
-
-.It Em PCVT_24LINESDEF
-If enabled, the 25-line modi
-.Po
-VT emulation with 25 lines, and HP emulation with 28 lines
-.Pc
-default to 24 lines only to provide a better compatibility to the
-original DEV VT220 (TM). Thus it should be possible to use the
-terminal information for those terminals without further changes.
-Note that this is a startup option; it is possible to toggle between
-the 24- and 25-lines' display by the
-.Xr scon 1
-utility.
-.br
-Default: off
-
-.It Em PCVT_EMU_MOUSE
-Emulate a three-button mouse via the keypad. Useful for notebooks when
-running XFree86. See
-.Sx Mouse emulation
-below.
-.br
-Default: off
-
-.It Em PCVT_META_ESC
-If enabled, a sequence composed of
-.Aq Em esc ,
-followed by the normal key code is emitted if a key is pressed with the
-.Aq Em Alt
-key modifier. If disabled, then normal key code with the value
-.Em 0x80
-added is sent.
-.br
-Default: off
-
-.El
-
-Note that there are further options available which are mainly used for
-debugging purposes or as a workaround for hardware problems. They are
-found in
-.Pa i386/isa/pcvt/pcvt_hdr.h
-along with their documentation.
-
-.Ss Internal Functions
-The functionality described below may be accessed via
-.Xr ioctl 2
-system calls with a file descriptor opened on a device node
-related to the
-.Nm pcvt
-driver.
-To make use of them, a program should contain the following line:
-
-
-.Dl #include <machine/pcvt_ioctl.h>
-
-Any parameter definitions cited below can be found in that file.
-
-
-.Em Keyboard related functions
-
-Three functions are related to basic keyboard hardware:
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDRESET
-reset keyboard, set defaults;
-.It KBDGTPMAT
-get current typematic value, parameter is a pointer to int where
-the values is stored to;
-.It KBDSTPMAT
-set current typematic value, similar to above command.
-.El
-
-Symbolic values are available for the appropriate constants.
-To specify the initial typematic delay time, they are
-KBD_TPD250 for 250 ms through
-KBD_TPD1000 for 1000 ms, in steps of 250 ms. The typematic repeat
-rates are
-KBD_TPM300, specifying 30.0 characters per second through
-KBD_TPM20 for 2.0 characters per second. The intermediate values
-are: 30.0, 26.7, 24.0, 21.8, 20.0, 18.5, 17.1, 16.0, 15.0, 13.3,
-12.0, 10.9, 10.0, 9.2, 8.6, 8.0, 7.5, 6.7, 6.0, 5.5, 5.0, 4.6, 4.3,
-4.0, 3.7, 3.3, 3.0, 2.7, 2.5, 2.3, 2.1, 2.0 characters per second.
-
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDGREPSW
-get key repetition switch, and
-.It KBDSREPSW
-set key repetition switch
-.El
-
-again take a pointer to int as argument. They manipulate the
-drivers internal keyboard repetition flag, possible values are:
-KBD_REPEATOFF or KBD_REPEATON.
-
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDGLEDS
-get LED state, and
-.It KBDSLEDS
-set LED state manipulate the keyboard indicators, but do not influence
-the drivers idea of lock key state.
-.El
-
-The int where the argument points to
-may have the values
-KBD_SCROLLLOCK, KBD_NUMLOCK, KBD_CAPSLOCK, which may be used in any
-conjunction.
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDGLOCK
-gets state of SCROLL,NUM,CAPS, and
-.It KBDSLOCK
-sets state of SCROLL,NUM,CAPS + LEDs
-.El
-
-should be used in a same manner to get/set the drivers internal
-LED flags.
-
-
-.Em Keyboard remapping
-
-One important feature of the
-.Nm pcvt
-driver is its ability to overload the built in key definition.
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDGCKEY
-get current key values,
-.It KBDSCKEY
-set new key assignment values, and
-.It KBDGOKEY
-get original key assignment values
-.El
-
-arrange those functions. The take a pointer to a
-.Em struct kbd_ovlkey
-as argument as described below. In addition,
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDRMKEY
-removes a key assignment, taking a pointer to an int as argument which
-contains the affected key number;
-.It KBDDEFAULT
-removes all key assignments.
-.El
-.Bd -literal
-struct kbd_ovlkey                /* complete definition of a key */
-{
-    u_short keynum;                      /* the key itself */
-    u_short type;                        /* type of key, see below */
-    u_char  subu;                        /* subtype, ignored on write */
-    char    unshift[KBDMAXOVLKEYSIZE+1]; /* emitted string, unshifted */
-    u_char  subs;                        /* subtype, ignored on write */
-    char    shift[KBDMAXOVLKEYSIZE+1];   /* emitted string, shifted */
-    u_char  subc;                        /* subtype, ignored on write */
-    char    ctrl[KBDMAXOVLKEYSIZE+1];    /* emitted string, control */
-    u_char  suba;                        /* subtype, ignored on write */
-    char    altgr[KBDMAXOVLKEYSIZE+1];   /* emitted string, altgr */
-};
-.Ed
-
-The appropriate values for the
-.Em type
-field are:
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBD_NONE
-no function, key is disabled,
-.It KBD_SHIFT
-keyboard shift,
-.It KBD_META
-alternate shift, sets bit8 to ASCII code,
-.It KBD_NUM
-numeric shift, keypad numeric / application mode,
-.It KBD_CTL
-control code generation,
-.It KBD_CAPS
-caps shift - swaps case of letter,
-.It KBD_ASCII
-ASCII code generating key,
-.It KBD_SCROLL
-stop output,
-.It KBD_FUNC    
-function key,
-.It KBD_KP
-keypad keys,
-.It KBD_BREAK
-ignored,
-.It KBD_ALTGR
-AltGr translation feature,
-.It KBD_SHFTLOCK
-shift lock,
-.It KBD_CURSOR
-cursor keys, and
-.It KBD_RETURN
-.Dq Return
-or
-.Dq Enter
-keys.
-.El
-
-The
-.Em subtype
-field contains one of the values
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBD_SUBT_STR
-key is bound to a string, or
-.It KBD_SUBT_FNC
-key is bound to a function.
-.El
-
-.Em Mouse emulation
-
-The mouse emulator
-.Pq if configured in
-fakes a three-button mouse using the Mouse Systems protocol. The first
-.Nm pcvt
-device node not used by a virtual screen is the mouse device. I.\& e.,
-for the default value of 8 virtual screens,
-.Pa /dev/ttyv0
-through
-.Pa /dev/ttyv7
-would refer to the virtual screens, and
-.Pa /dev/ttyv8
-were the mouse emulator device. The mouse emulation is turned on by
-pressing the
-.Aq Em NumLock
-key. The pointer is moved by the numerical keypad keys, into the
-obvious directions. The pointer is initially moved in single steps,
-and is accelerated after an adjustable time
-.Pq default: 500 ms
-by about 6 times. The mouse buttons are emulated by three normal
-keys, by default the function keys
-.Aq Em \&F1 ,
-.Aq Em \&F2 ,
-and
-.Aq Em \&F3 .
-There are two selectable flavors available: normal and
-.Dq sticky
-buttons. Normal buttons behave as expected.
-.Dq Sticky
-buttons are notified as button-press on the first keypress. They
-.Dq stick
-until the key is pressed again
-.Pq or another button-emulating key instead .
-Button presses and releases are notified to the user by a simple
-.Dq pling ,
-or
-.Dq plong ,
-respectively, generated from the PC's built-in speaker.
-
-The following commands control the emulation.
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDMOUSEGET
-get the current definitions, and
-.It KBDMOUSESET
-set new definitions.
-.El
-
-Both accept a
-.Li struct mousedefs *
-as the third argument to the ioctl call:
-.Bd -literal
-struct mousedefs {
-    int leftbutton;     /* (PC) scan code for "left button" key     */
-    int middlebutton;   /* (PC) scan code for "mid button" key      */
-    int rightbutton;    /* (PC) scan code for "right button" key    */
-    int stickybuttons;  /* if true, the buttons are "sticky"        */
-    int acceltime;      /* timeout in microseconds to start pointer */
-                        /* movement acceleration                    */
-    /* defaults to: scan(F1), scan(F2), scan(F3), false, 500000     */
-};
-.Ed
-
-
-.Em Downloadable character set interface
-
-EGA and VGA video adaptors provide the capability of downloadable
-software fonts. Since the
-.Sq native character set
-of any IBM-compatible PC video board does not allow the full interpretation
-of DEC multinational character set or ISO Latin-1
-.Pq ISO 8859-1 ,
-this might be very useful for a U**X environment.
-
-.Bl -tag -width 20n -offset indent -compact
-.It VGASETFONTATTR
-set font attr, and
-.It VGAGETFONTATTR
-get font attr
-.El
-
-are used to manipulate the drivers information about a downloaded
-font. The take a pointer to a
-.Em struct vgafontattr
-as argument:
-.Bd -literal
-struct vgafontattr {
-    int character_set;          /* VGA character set */
-    int font_loaded;            /* Mark font loaded or unloaded */
-    int screen_size;            /* Character rows per screen */
-    int character_scanlines;    /* Scanlines per character - 1 */
-    int screen_scanlines;       /* Scanlines per screen - 1 byte */
-};
-.Ed
-
-Each character of each font is to be downloaded with
-
-.Bl -tag -width 20n -offset indent -compact
-.It VGALOADCHAR
-load vga char,
-.El
-
-taking a pointer to
-.Em struct vgaloadchar
-as its argument:
-.Bd -literal
-struct vgaloadchar {
-    int character_set;       /* VGA character set to load into */
-    int character;           /* Character to load */
-    int character_scanlines; /* Scanlines per character */
-    u_char char_table[32];   /* VGA character shape table */
-};
-.Ed
-
-The field
-.Em character_set
-takes the values
-CH_SET0, CH_SET1, CH_SET2, CH_SET3 on EGA's or VGA's. Since VGA's
-might have up to eight simultaneously loaded fonts, they can take
-CH_SET4, CH_SET5, CH_SET6, or CH_SET7, too.
-
-Note that there's a dependence between the font size
-and a possible screen height
-.Pq in character rows ,
-depending on the video adaptor used:
-.Bd -literal
-Screen size (rows) on:          EGA             VGA
-Font size
-
-8 x 8                           43              50
-8 x 10                          35              40
-8 x 14                          25              28
-8 x 16                          not             25

-.Ed
-
-
-.Em General screen manipulation commands
-
-.Bl -tag -width 20n -offset indent -compact
-.It VGACURSOR
-sets cursor shape,
-.El
-
-taking a pointer to the following structure as argument:
-.Bd -literal
-struct cursorshape {
-    int screen_no; /* screen number for which to set,               */
-                   /*  or -1 to set on current active screen        */
-    int start;     /* top scanline, range 0... Character Height - 1 */
-    int end;       /* end scanline, range 0... Character Height - 1 */
-};
-.Ed
-
-.Bl -tag -width 20n -offset indent -compact
-.It VGASETSCREEN
-set screen info, and
-.It VGAGETSCREEN
-get screen info,
-.El
-
-provide an interface to some general driver internal variables
-which might modify the behaviour of the screens,
-or which might simply be used to force the driver to switch
-to one certain screen. Their argument is a pointer to the structure:
-.Bd -literal
-struct screeninfo {
-    int adaptor_type;   /* type of video adaptor installed     */
-                        /* read only, ignored on write (yet!)  */
-    int totalfonts;     /* no of downloadable fonts            */

-running an X server. They are ugly with respect to the implied semantics
-.Pq i.\& e., they break Berkeley semantics
-and are therefore not recommended for common use. See the file

-.El
-
-.Ss Configuration
-The
-.Nm pcvt
-console driver is currently available for the Intel-based BSD operating
-systems
-.Tn NetBSD/i386
-(release 0.9 or higher),
-and
-.Tn FreeBSD
-(release 1.0-GAMMA or higher) .
-In order to get the appropriate system support, one of the options
-.Em PCVT_NETBSD ,
-or
-.Em PCVT_FREEBSD
-must be defined in the system's config file
-.Pq see Xr config 8 .
-In addition, for the
-.Tn FreeBSD
-and
-.Tn NetBSD
-operating systems, it is necessary to set this option to the operating
-system's version number.
-For
-.Tn FreeBSD
-this version number must be expressed as a 3-digit number.
-E.\& g., if you are running the 1.0 release
-.Pq which is actually version 1.0.2 ,
-you should define
-
-.Em PCVT_FREEBSD = 102
-
-For
-.Em NetBSD
-this version number must be expressed as 9 if you are running NetBSD 0.9
-and anything greater than 9 for NetBSD-current (pre 1.0). It is recommended
-to use (as with
-.Tn FreeBSD )
-100 for
-.Nx 1.0
-and 999 for
-.Tn NetBSD-current.
-E.g., if you are running the
-.Nx 1.0
-release, you should define
-
-.Em PCVT_NETBSD = 100
-
-The
-.Nm pcvt
-driver has been designed to be highly configurable in order to satisfy
-everyone's needs. The preferred way for those configurations is to
-provide appropriate
-.Em options
-lines within the config file, possibly overriding the built-in default
-values. Therefore it is possible to compile several distinct kernels
-with different driver behaviour on a single machine.
-
-The following list gives a short overview of the available configuration
-options. Refer to the file
-.Pa i386/isa/pcvt/pcvt_hdr.h
-in the kernel source tree for detailed documentation.
-
-Note: the following conventions apply to all the Boolean options.
-If an option is given with no value, a value of 1
-.Pq activated
-is substituted. If an option value is given as 0, this options is
-deactivated. Any other value is substituted by 1, too. If an option
-is omitted, a built-in default is assumed.
-
-.Bl -tag -width indent -compact
-
-.It Em PCVT_NSCREENS
-Defines the number of virtual screens.
-.br
-Default: 8
-
-.It Em PCVT_VT220KEYB
-If activated, a keyboard layout resembling a DEC VT200 (TM) is generated.
-If deactivated, a mixture between VT220 and HP is used. See the files
-.Pa Keyboard.VT
-and
-.Pa Keyboard.HP
-in the
-.Nm pcvt
-documentation directory for a full description.
-.br
-Default: off
-
-.It Em PCVT_SCREENSAVER
-Enables the builtin screensaver feature.
-.br
-Default: on
-
-.It Em PCVT_PRETTYSCRNS
-If enabled, a blinking-star screensaver is used. If disabled, the screen
-is simply blanked
-.Pq which might be useful for energy-saving monitors .
-.br
-Default: on
-
-.It Em PCVT_CTRL_ALT_DEL
-If enabled, the key combination
-.Aq Em Ctrl
-.Aq Em Alt
-.Aq Em Del
-invokes a CPU reset.
-.br
-Default: off
-
-.It Em PCVT_USEKBDSEC
-Do NOT override a security lock for the keyboard.
-.br
-Default: on
-
-.It Em PCVT_24LINESDEF
-If enabled, the 25-line modi
-.Po
-VT emulation with 25 lines, and HP emulation with 28 lines
-.Pc
-default to 24 lines only to provide a better compatibility to the
-original DEV VT220 (TM). Thus it should be possible to use the
-terminal information for those terminals without further changes.
-Note that this is a startup option; it is possible to toggle between
-the 24- and 25-lines' display by the
-.Xr scon 1
-utility.
-.br
-Default: off
-
-.It Em PCVT_EMU_MOUSE
-Emulate a three-button mouse via the keypad. Useful for notebooks when
-running XFree86. See
-.Sx Mouse emulation
-below.
-.br
-Default: off
-
-.It Em PCVT_META_ESC
-If enabled, a sequence composed of
-.Aq Em esc ,
-followed by the normal key code is emitted if a key is pressed with the
-.Aq Em Alt
-key modifier. If disabled, then normal key code with the value
-.Em 0x80
-added is sent.
-.br
-Default: off
-
-.El
-
-Note that there are further options available which are mainly used for
-debugging purposes or as a workaround for hardware problems. They are
-found in
-.Pa i386/isa/pcvt/pcvt_hdr.h
-along with their documentation.
-
-.Ss Internal Functions
-The functionality described below may be accessed via
-.Xr ioctl 2
-system calls with a file descriptor opened on a device node
-related to the
-.Nm pcvt
-driver.
-To make use of them, a program should contain the following line:
-
-
-.Dl #include <machine/pcvt_ioctl.h>
-
-Any parameter definitions cited below can be found in that file.
-
-
-.Em Keyboard related functions
-
-Three functions are related to basic keyboard hardware:
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDRESET
-reset keyboard, set defaults;
-.It KBDGTPMAT
-get current typematic value, parameter is a pointer to int where
-the values is stored to;
-.It KBDSTPMAT
-set current typematic value, similar to above command.
-.El
-
-Symbolic values are available for the appropriate constants.
-To specify the initial typematic delay time, they are
-KBD_TPD250 for 250 ms through
-KBD_TPD1000 for 1000 ms, in steps of 250 ms. The typematic repeat
-rates are
-KBD_TPM300, specifying 30.0 characters per second through
-KBD_TPM20 for 2.0 characters per second. The intermediate values
-are: 30.0, 26.7, 24.0, 21.8, 20.0, 18.5, 17.1, 16.0, 15.0, 13.3,
-12.0, 10.9, 10.0, 9.2, 8.6, 8.0, 7.5, 6.7, 6.0, 5.5, 5.0, 4.6, 4.3,
-4.0, 3.7, 3.3, 3.0, 2.7, 2.5, 2.3, 2.1, 2.0 characters per second.
-
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDGREPSW
-get key repetition switch, and
-.It KBDSREPSW
-set key repetition switch
-.El
-
-again take a pointer to int as argument. They manipulate the
-drivers internal keyboard repetition flag, possible values are:
-KBD_REPEATOFF or KBD_REPEATON.
-
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDGLEDS
-get LED state, and
-.It KBDSLEDS
-set LED state manipulate the keyboard indicators, but do not influence
-the drivers idea of lock key state.
-.El
-
-The int where the argument points to
-may have the values
-KBD_SCROLLLOCK, KBD_NUMLOCK, KBD_CAPSLOCK, which may be used in any
-conjunction.
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDGLOCK
-gets state of SCROLL,NUM,CAPS, and
-.It KBDSLOCK
-sets state of SCROLL,NUM,CAPS + LEDs
-.El
-
-should be used in a same manner to get/set the drivers internal
-LED flags.
-
-
-.Em Keyboard remapping
-
-One important feature of the
-.Nm pcvt
-driver is its ability to overload the built in key definition.
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDGCKEY
-get current key values,
-.It KBDSCKEY
-set new key assignment values, and
-.It KBDGOKEY
-get original key assignment values
-.El
-
-arrange those functions. The take a pointer to a
-.Em struct kbd_ovlkey
-as argument as described below. In addition,
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDRMKEY
-removes a key assignment, taking a pointer to an int as argument which
-contains the affected key number;
-.It KBDDEFAULT
-removes all key assignments.
-.El
-.Bd -literal
-struct kbd_ovlkey                /* complete definition of a key */
-{
-    u_short keynum;                      /* the key itself */

-.Em Mouse emulation
-
-The mouse emulator
-.Pq if configured in
-fakes a three-button mouse using the Mouse Systems protocol. The first
-.Nm pcvt
-device node not used by a virtual screen is the mouse device. I.\& e.,
-for the default value of 8 virtual screens,
-.Pa /dev/ttyv0
-through
-.Pa /dev/ttyv7
-would refer to the virtual screens, and
-.Pa /dev/ttyv8
-were the mouse emulator device. The mouse emulation is turned on by
-pressing the
-.Aq Em NumLock
-key. The pointer is moved by the numerical keypad keys, into the
-obvious directions. The pointer is initially moved in single steps,
-and is accelerated after an adjustable time
-.Pq default: 500 ms
-by about 6 times. The mouse buttons are emulated by three normal
-keys, by default the function keys
-.Aq Em \&F1 ,
-.Aq Em \&F2 ,
-and
-.Aq Em \&F3 .
-There are two selectable flavors available: normal and
-.Dq sticky
-buttons. Normal buttons behave as expected.
-.Dq Sticky
-buttons are notified as button-press on the first keypress. They
-.Dq stick
-until the key is pressed again
-.Pq or another button-emulating key instead .
-Button presses and releases are notified to the user by a simple
-.Dq pling ,
-or
-.Dq plong ,
-respectively, generated from the PC's built-in speaker.
-
-The following commands control the emulation.
-
-.Bl -tag -width 20n -offset indent -compact
-.It KBDMOUSEGET
-get the current definitions, and
-.It KBDMOUSESET
-set new definitions.
