  24 /*  FUNCTION
  25         SetMode() can be used to change a console handler between
  26         RAW: mode and CON: mode.
  27
  28     INPUTS
  29         fh      -   The filehandle describing the console.
  30         mode    -   The new mode of the console:
  31                         1   - RAW: mode
  32                         0   - CON: mode
  33
  34     RESULT
  35         This function will return whether it succeeded:
  36
  37         == DOSTRUE  console mode changed
  38         != DOSTRUE  console mode change failed.
