MAPSCRN(8)                             System Manager's Manual                            MAPSCRN(8)



NAME
       mapscrn - load screen output mapping table

SYNOPSIS
       mapscrn [-V] [-v] [-o map.orig] mapfile

DESCRIPTION
       The  mapscrn  command  is obsolete - its function is now built-in into setfont.  However, for
       backwards compatibility it is still available as a separate command.

       The mapscrn command loads a user defined output character  mapping  table  into  the  console
       driver.  The console driver may be later put into use user-defined mapping table mode by out‐
       putting a special escape sequence to the console device.  This sequence is <esc>(K for the G0
       character set and <esc>)K for the G1 character set.  When the -o option is given, the old map
       is saved in map.orig.

USE
       There are two kinds of mapping tables: direct-to-font tables, that give a font  position  for
       each  user  byte  value,  and  user-to-unicode tables that give a unicode value for each user
       byte. The corresponding glyph is now found using the unicode index of the font.  The command
              mapscrn trivial
       sets up a one-to-one direct-to-font table where user bytes directly address the font. This is
       useful for fonts that are in the same order as the character set one uses.  A command like
              mapscrn 8859-2
       sets up a user-to-unicode table that assumes that the user uses ISO 8859-2.

INPUT FORMAT
       The mapscrn command can read the map in either of two formats:
       1. 256 or 512 bytes binary data
       2. two-column text file
       Format  (1)  is  a direct image of the translation table. The 256-bytes tables are direct-to-
       font, the 512-bytes tables are user-to-unicode tables.  Format (2) is used to fill the  table
       as follows: cell with offset mentioned in the first column is filled with the value mentioned
       in the second column.  When values larger than 255 occur, or values  are  written  using  the
       U+xxxx  notation,  the  table is assumed to be a user-to-unicode table, otherwise it is a di‐
       rect-to-font table.

       Values in the file may be specified in one of several formats:
       1. Decimal: String of decimal digits not starting with '0'
       2. Octal: String of octal digits beginning with '0'.
       3. Hexadecimal: String of hexadecimal digits preceded by "0x".
       4. Unicode: String of four hexadecimal digits preceded by "U+".
       5. Character: Single character enclosed in single quotes. (And the  binary  value  is  used.)
       Note that blank, comma, tab character and '#' cannot be specified with this format.
       6. UTF-8 Character: Single (possibly multi-byte) UTF-8 character, enclosed in single quotes.

       Note  that control characters (with codes < 32) cannot be re-mapped with mapscrn because they
       have special meaning for the driver.

OTHER OPTIONS
       -V     Prints version number and exits.

       -v     Be verbose.

FILES
       /usr/share/consoletrans
              The default directory for screen mappings.
