Mapping console screen fonts

You can use vidi to display the full range of characters on a display adapter. Normally, if you have a console with a display adapter which has a character set defined in a ROM, you will be able to display only those characters defined in that ROM. In addition, the mapchan(F) file for the console must correspond to the character set defined in the display adapter ROM to display the entire font set.

For example, if your display adapter ROM has the IBM PC character set defined, but you are using the PC Nordic mapchan file, you will not be able to display the following characters:

ø   Ø   L·   l·   õ   Õ   ã   Ã

To display these characters, use vidi to override the character set in ROM with the PC Nordic font file.

In addition to using vidi to override the ROM character set, you can use it to define certain display fonts on some display adapters. For example, the VGA adapter will allow you to display fonts in the sizes 8x8, 8x14, and 8x16.

If you change mapchan mapping for a console with any type of display adapter, you may also need to change the character font correspondingly.

vidi defines the font for one of a number of character sets. The font definition files are available in the directory /usr/lib/vidi, and are listed in ``Screen font mapping for the console'' for the various character sets.

For example, the following command allows you to display the full range of Nordic characters when you are using the PC Nordic mapchan file and your display adapter ROM has the IBM PC character set defined:

vidi -f /usr/lib/vidi/nor.8x14 font8x14

Screen font mapping for the console

If you change the mapchan(M) mapping for a console with any type of display adapter, you will also need to change the character font.

vidi defines the font for one of the character sets given below. The following font definition files are available in the directory /usr/lib/vidi:

Limitations

The internal and external commands should only be used on Compaq compatible displays.

You must select the mode no9bit before loading ISO8859.* fonts. This is to prevent characters appearing corrupted in certain localized codesets.
