Purpose
Function 1 Uses reserved Code 128 characters (UCC/EAN128).
Function 2
Appends data (subsets A and B only). The result is not
readable by all bar code scanners.
Function 3 Initializes a bar code scanner.
Function 4
Extends characters by adding 128 to the ASCII code. For
example, 'a' (97 decimal) is changed to 'β' (225 decimal) by
adding 128 to it. This function is unavailable in subset C.
