I have a question about using VioSetMode. I find that it only works
some times. If I have the display in 80*50 mode and use VioSetMode
to change it to 80*25, it works. However, if I'm in other modes such
as 80*34 it does not work at all. And if I'm in 80*12 or 80*43, it
only partially works. Although the screen changes to the correct 
number of lines, the font is not the default font.

I have enclosed the code I'm using to test this. Any help would be
appreciated.

   BYTE bCell[2];

   bCell[0] = 0x20;      /* space character       */
   bCell[1] = 0x07;      /* white attribute (EGA) */

//   VioScrollDn(0, 0, 0xFFFF, 0xFFFF, 0xFFFF, bCell, 0);
//   VioSetCurPos(0, 0, 0);

   viomi.cb = sizeof(viomi);
   VioGetMode(&viomi, 0);

   viomi.row = 25;
   viomi.col = 80;
   VioSetMode(&viomi, 0);
}
