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