InbvPortEnableFifo(
  IN  ULONG  DeviceId,
  IN  BOOLEAN bEnable
  );

Routine Description:

    This routine will attempt to enable the FIFO in the 16550 UART.
    Note that the behaviour is undefined for the 16450, but practically,
    this should have no effect.

Arguments:

    DeviceId - Value returned by InbvPortInitialize()
    bEnable  - if TRUE, FIFO is enabled
               if FALSE, FIFO  is disabled

Return Value:

    None
