The serial port is implicitly closed when the serial library is unloaded
(even if the original app forgets to close it). The only case I know of
where the port may still be in use is with a keyboard driver. In that case,
you will need to find out how to tell the specific driver to release the
port (if possible). Otherwise your just out of luck until you reset or
manually unload the driver.
Do you have a specific case where the serial port is already in use and
locking you out? Or is just some speculative code to prevent a possible
problem?
