The last set of registers starting from #141 represents ASCII strings. Each reg-
ister is holding two ASCII characters. End of the string should be marked with
integer number of zero (‘0’). For example, if the AnalyzerName variable is set to
“Dev”, the holding register values are (considering that high byte located rst)
#141 ( 68, 101) and #142 ( 118, 0 ). Note that zero (‘0’) indicates the end of the
ASCII string.
