RESETDIG.EXE resets a DigiBoard COM/Xi so that the program can
  communicate with the board directly instead of using Interrupt 14
  calls which are slower and prone to problems if there is a bug in
  the DigiBoard Device Driver.

  If using the DIGIBOARD Direct Interface, this program needs
  to be placed in your AUTOEXEC.BAT file so that the DigiBoard can
  be reset evertime you boot your computer. The program initializes
  the DigiBoard so that it can talk to to the board directly.

  To execute RESETDIG.EXE, pass the following 2 Command Line
  arguments to it:

    Base Address = C000, C800, D000, or D800
    I/O Port     = 100, 110, 120, 200, 220, 300, or 320

  RESETDIG D000 320
  RESETDIG D800 300

  The arguments you pass are the Memory Window Address and the
  I/O Port Address you configured your DigiBoard to use.
