       KON - Kanji cONsole emulator

       kon [ video ] [ -capability value ...  ]

       KON is a program to display Kanji characters on a virtual console of Linux and FreeBSD.

       KON  uses pty(4) to hook the I/O for console, and displays Kanji characters by drawing the
       image of them on VGA or DCGA.

       KON can be invoked from another KON. In this situation, new KON runs on newly opened  vir-
       tual console.

       KON  has ability to interpret some options to specify the video driver to be used, or some
       other environmental conditions.	video is to specify one of video driver  entries  written
       in  kon.cfg.   If this option is omitted, then NORMAL video driver is used.  Some settings
       as such as CursorInterval can be overridden by -capability options. For example,

	  % kon -CursorInterval 10

       invokes the kon with setting the value of CursorInterval to 10.

       kon.cfg is the file to configure the behaviour of KON.  Video drivers and Palettes used by
       KON is specified in this file.  The format of an entry for this file is:


       There   are   no  distinction  about  case  (upper/lower)  in  EntryName.   Any	line  for
       "Value_for_Entry" must start with TAB.  The part from # to the end of line, is treated  as

       Types of "Value_for_Entry" are:

       boolean	 On / Off (no distinction about upper/lower case)

       choice	 select one from options (no distinction about upper/lower case)

       numeric	 Decimal Number

       string	 Each entry has it's special format.

       Following two entries are essential in this configuration file:

	   specify the video driver to be used. Available options are:

	   VGA	    driver for VGA, SVGA, EGA
	   VGAFM    same above but with ability of font deformation
	   J3100SX  driver for TOSHIBA J3100SX (DCGA)

	   VGA and VGAFM require some parameters for
	    VGA  register  value,  screen  size(Number	of  dots),  Width(Number  of characters),
	   Hight(Number of lines).

	   Users can use this entry to change the total number of characters to be displayed, but
	   except  for VGA resolution(640x480), the number of characters that can be seen for the
	   specified VGA register value, depends the video cards.  Default kon.cfg set NORMAL  as
	   an alias for the standard VGA, and has some alternate entries for some video cards.

	   specify  the  command  to be invoked at the start of KON.  One line for each commands,
	   but multiple lines can be specified.  The command to load the fonts must be	specified
	   here.   When  the  fonts for ASCII alphanumeric have not been loaded, then VGA font is

	   for the fonts file which is not compressed
	     <fontloader> <Font file for ASCII alphanumeric>
	     <fontloader> <Kanji/Kana font file>
	   for the fonts file which is compressed
	     zcat <compressed font fine for ASCII alphanumeric> | <fontloader>
	     zcat <compressed font file for Kanji/Kana> | <fontloader>

       Next entry is required when VGA or VGAFM is specified as video driver:

	      specify the Pallete. The format is the pallette value(decimal) for  R,G,B  in  each
	      line, and 16 lines are there total.  Default kon.cfg has STDPEL and REVPEL entries.
	      STDPEL is the standard palette, and REVPEL is the reverse.  PELS can  be	specified
	      as an alias for used entry.

       Other entries are:

	   specify  the  mouse	driver. Select a type of mouse from Microsoft, MouseSystems, Bus-
	   Mouse, MMSeries, Logitech, None None is default.

	   specify the baud rate for serial mouse.  Select  one  from  1200,  2400,  4800,  9600.
	   Default  is	1200. This is enabled when MOUSE is specified as others than NONE or Bus-

	   specify the device name of Mouse. Default is /dev/mouse.  This is enabled  when  MOUSE
	   has the entry other than None.

	   specify if the Mouse is 3-button type. Default is Off.

	   specify  wheter  hardware scroll is used or not. Default is On.  This is effective for
	   VGA, VGAFM, J3100SX.

	   specify the length of beep sound in the unit of 1/100 sec.  Default is 5.

	   specify the interval of cursor blinking in the unit of 1/10 sec.   Default  is  4.  To
	   stop the blinking, specify 0.

	   specify  the  amount of time to start the screen saver in the unit of minutes. Default
	   is 4.

	   specify if wide cursor is used on Kanji characters, or ot.  Default is On.

	   specify the size of cursor box using these two entries.
		 0 +--------+
		   |	    |
		   |--------| <-- CursorTop
		15 +--------+ <-- CursorBottom
	   These are effective for VGA, VGAFM, and CGA drivers.

	   specify if the shape of cursor is box or under line.  Default is  Off.  Effective  for
	   only J3100SX driver.

	   specify  if the font data on 3rd page in VGA memory is saved.  This is useful for Tri-
	   dent video cards. Default is Off.  Effective for VGA, VGAFM drivers.

	   specify the offset value for VGA font. Default is 0.  When the VGA fonts are  used  as
	   ASCII alphanumeric font, there are some PCs the lower parts of characters are missing.
	   In those circumstance, this entry can be used to  adjust  the  position  of	displayed

	   specify the default font and the coding in 1bit.  The formats are:

		<SB font> <DB font> [EUC|SJIS]

	   SB font and DB font can be selected from:

	   SB font: Single Byte font
		ISO8859-6,ISO8859-7,ISO8859-8,ISO8859-9,      JISX0201.1976-0

	   DB font: Double Byte font

	   specify if the greeting message is shown at startup. Default is On.

Configuratino for High resolution screen.
       When VGA or VGAFM is used as video driver, KON can use the wider space for text area  with
       the fine-tuing at kon.cfg.

		<VGA or VGAFM>
		[decimation factor for VGAFM]
		<HR> <HS> <HE> <HFL> <VR> <VS> <VE> <VFL>
		<Clock Number>
		<Line Width - 1> <Line Numbers - 1>

       Control	parameter in 3rd line for VGAFM (2nd line for VGA) consists of 8 decimal numbers.
       These numbers are similar as the video mode lines in XF86Config.   KON  can  emulate  text
       upto 800x600 resolution.

       Screen control parameters:
	   HR total dot number in horizontal
	   HS the start point of horizontal sync
	   HE the end point of horizontal sync
	   HFL Total number of horizontal frames
	   VR number of vertical lines
	   VS the start point of vertical sync
	   VE the end point of vertical sync
	   VFL total number of vertical frames

       Clock  Number selects the clock frequency for the mode of that entry. Only lowest 2 bit is
       effective, i.e. a number from 0 to 3 can be specified here.  The last line  specifies  the
       area for text screen to emulate.

       /etc/kon.cfg		Configuratin file
       /usr/share/fonts/kon/*	Font files

       - When text screen is in high resolution mode at
	 the start of Linux, KON can not work
	 successfully since the size of VGA font is
	 different from usual.
       - When multiple entries with same name in kon.cfg,
	the first entry is used. The maximum length of one line
	is 255 bytes.
