                     when it cannot be completed synchronously. The receive thread
                     runs at the priority given here, and the transmit thread
                     runs at the next lower priority.
                     The exact priority needed here depends on the importance of the
                     PPP subsystem relative to the rest of the system. The default
                     is to put it in the middle of the priority range to provide
