NAMEmapscrn - load screen output mapping table
SYNOPSISmapscrn [-v] [-o map.orig] mapfile
DESCRIPTIONThe mapscrn command is obsolete - its function is now built-in into setfont.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 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.
USEThere 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
- mapscrn 8859-2
INPUT FORMATThe 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 direct-to-font table.
Values in the file may be specified in one of several
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.
FILES/lib/kbd/consoletrans is the default directory for screen mappings.
