    I believe that OpenDriver, when called, will not re-initialize a
device if it is already opened. At least, the driver should have
been written to only open one.
    You should leave it open if you are planning on calling your
routine that opens and closes it often, and write a small routine that
just closes it. The close routine could be called from the program, when
it knows that its done with the driver.
