You can display the full range of characters on a display adapter by using the vidi(C) utility. 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, in order to display the entire font set, the mapchan file for the console must correspond to the character set defined in that ROM.
In addition to using vidi(C) to override ROM, 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.
The vidi(C) utility defines the font for one of these six character sets.
