Control Sets
In general, standard bar code symbologies will only encode the ASCII character set. Function keys, arrow keys and many other “extended” keys on an IBMcompatible keyboard do not translate to ASCII characters. One method of “bar coding” the extended keys is to substitute the extended key codes when a specific ASCIIcontrol character is found in the bar code stream. The Control Sets are specific translations of the ASCII (HEX) set.
