Interrogation Commands

The DMC-18x2 has a set of commands that directly interrogate the controller. When these commands
are entered, the requested data is returned in decimal format on the next line followed by a carriage
return and line feed. The format of the returned data can be changed using the Position Format (PF),
and Leading Zeros (LZ) command. For a complete description of interrogation commands, see chapter
5.
