This utility requires the Seiko Epson video BIOS.
In a Windows DOS box, the DOS box text mode is emulated with graphics. Text modes are not actually text
modes at all, but are graphics modes. Running VRTEXP in this case behaves as would be expected when
running in graphics mode. Switching to a full screen DOS box using <ALT>-<Enter> switches the emulated
text mode to an actual text mode and the program will then behave normally.
