When requested with a mnemonic instruction, the
TPG 26x transmits the measurement data or parameters
as ASCII strings to the HOST.
<ENQ> must be transmitted to request the transmission
of an ASCII string. Additional strings, according to the
last selected mnemonic, are read out by repetitive
transmission of <ENQ>.
If <ENQ> is received without a valid request, the
ERROR word is transmitted.
