<filename>.fon</filename>, <filename>.fnt</filename>
Bitmapped screen fonts
The <filename>.fot</filename> is used by <trademark class="registered">Windows</trademark> as sort of a symbolic link to the actual <trademark class="registered">TrueType</trademark> font (<filename>.ttf</filename>) file. The <filename>.fon</filename> font files are also used by Windows. I know of no way to use this font format with FreeBSD.
What Font Formats Can I Use?
Which font file format is useful depends on the application being used. FreeBSD by itself uses no fonts. Application programs and/or drivers may make use of the font files. Here is a small cross reference of application/driver to the font type suffixes:
Driver
vt
<filename>.hex</filename>
syscons
<filename>.fnt</filename>
