Note: All bytes of that transmission are ASCII characters.
Note: Changing settings using #1 functions during measurements running state (#1,S1;) is
blocked. Stop the measurements (#1,S0;) before changing the settings.
In order to read out all current control settings the user should send to the device the following sequence of
characters:
#1;
In this case the instrument outputs all control settings given in A.3 Control setting codes in the format:
#1,Xccc,Xccc,(...),Xccc;
Example: The instrument sends the following sequence of characters as an answer for the mentioned above
