One application should be given the responsibility of opening and closing the port.
Once the port is opened, simply pass the opened port ref to the other application,
keeping in mind that if you use the wakeup handler mechanism, you must be certain the
wakeup proc is loaded, locked, and ready to handle an interrupt-service-level callback.
In general, it's not a good idea to write your application(s) this way, but you may
have specific needs which require such an architecture.
