MAPSCRN (8)
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.
