Mnemonic

The header mnemonic is formed from ASCII codes for A to Z, 0 to 9, and an underscore (_).
ASCII's A to Z characters are not case-sensitive. In other words, there is no distinction between
uppercase and lowercase letters, as they are interpreted in the same way.
In this instrument, the response message unit created corresponding to the query is composed of
only data part without header.
The mnemonic of the data part of the response message that the instrument sends is always
upper-case.
