Included in this directory is vga.bdf, a PC-font that allows you to
see the IBM high characters popular on DOS BBS systems. The font comes
with the X server sources. To use it, do the following:

uncompress vga.bdf.Z 
bdftopcf -o vga.pcf vga.bdf
cp vga.pcf /usr/lib/X11/font/misc 
(or wherever the fonts are kept on your system)
cd /usr/lib/X11/font/misc 
mkfontdir
xset fp rehash

Then start an xterm with
xterm -font vga

To use with Seyon, put the line

Seyon.vt100.font: vga

in your ~/.Xresources file, or invoke Seyon as

seyon -- -font vga

Good luck!
