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 formats:
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 follows: 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 formats:
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.
