  What is the *correct* order to close a device and free buffer memory &
replyports?
  The RKM examples does this in several ways, but my cautious mind says that
one should *first* close the device to prevent access to buffers etc, *then*
free the buffers. It looks like the RKM examples would work in 99% of the
cases...

  Currently, I'm doing this (where ReadRequest is a struct IOExtSer *):

  if (ReadRequest) {
      CloseDevice(ReadRequest);
      DeletePort(ReadRequest->IOSer.io_Message.mn_ReplyPort);
      FreeMem(ReadRequest, sizeof(*ReadRequest));
  }
