RETURNED ANSWER:
Axxxx The new setpoint which was sent
followed by a carriage return, line
feed.
If the command was sent #01C01300g01, the
capacity control setpoint would be changed
to 30.0g and the returned answer is A300g
followed by a carriage return, line feed.
If the command sent was #01C0711001, the MLC
force unload setpoint would be changed to
110% and the returned answer is A110 fol-
lowed by a carriage return, line feed.
If the command sent was #01C0520002, the
returned answer is BAD followed by the ID
number and a carriage return, line feed.
