ECTION
In general, standard bar code symbologies will only encode the ASCII character set.
Function keys, arrow keys and many other "extended" keys on an IBM compatible
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 ASCII control character
found in the bar code stream. The Control Sets are specific translation of the ASCII
(HEX) set.
