mapscrn

NAME

       mapscrn - load screen output mapping table

SYNOPSIS

       mapscrn [ -o map.orig ] mapfile

DESCRIPTION

       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 outputting 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.

OPERATION

       The mapscrn command can read the map in either of two for-
       mats:
       1. 256 byte binary data
       2. two-column text file
       Format (1) is is an image of translation table.  Any  time
       a  character  with  the  code  i  is output to the console
       device, the character with the code  table[i]  appears  on
       the  screen.  Format (2) is used to fill the table as fol-
       lows: cell with offset mentioned in the  first  column  is
       filled with the value mentioned in the second column.

       Values  in  the  file may be specified in one of four for-
       mats:
       1. Decimal: string of decimal digits  not  beginning  with
       '0'
       2. Octal: string of octal digits beginning with '0'
       3.  Hexadecimal:  string of hexadecimal digits preceded by
       "0x"
       4. Character: Single character enclosed in single  quotes.
       Note  that  blank,  comma, tab character and '#' cannot be
       specified with the 4th format.

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