<csum> = checksum of the string data. It is calculated performing the exclusive OR (XOR) of all cha-
racters from STX (or from <ind>) to ETX excluded the latter; the result of the XOR is decomposed into
2 characters considering separately the upper 4 bits (first character) and lower 4 bits (second cha-
racter); the 2 characters obtained are then ASCII encoded (example: XOR = 5Dh; <csum> = "5Dh"
namely 35h and 44h).
