New Master Load Status
The new master status responds with the number of the next master position to be loaded, where 0 represents "idle" or "no master to be loaded."
Example: If the user has the Master Symbol Database Size set to 1, and then either sends a <G> or toggles an active New Master Pin, the state will be 1, and prior to reading and effectively loading position 1, the response to <NEWM> would be <NEWM/1>. Once a symbol has been read and loaded, the status will be cleared: <NEWM/0>.
