program FX80;

{   This program will control most of the frequently used -- and
 also some infrequently used -- configuration parameters for the
 Epson FX80.  The code compiles 'as is' using TURBO Pascal.  Feel
 free to modify it in any way.  A nice project might be a font
 creation routine.  Please get word to me concerning any changes.
 I'd like to see them.  Go to it!
