The Wait-to-Continue command prevents the device from executing any further commands or queries until execution of all previous commands or queries have been completed. It differs from the *OPC? command in that it blocks within the GSG. It also resumes operation and allows synchronous execution of a command sequence within the GSG 10Hz epoch.
Wait until scenario is running and then request NMEA position.
