Position report in encoder mode on the PC21

Here is a helpful hint on the PC21: When in encoder mode the PC21 will not report back steps if not commanding a move. In other words, if someone was to turn the encoder by hand without commanding a move (the general method for testing an encoder), and ask for the position before and after the move, the position report will not change. If put in position maintenance though, it will try to keep its position even if a move is not commanded.
