Full ASCII
If Full ASCII Code 39 decoding is enabled, certain character
pairs within the bar code symbol will be interpreted as a single
character. For example: $V will be decoded as the ASCII character
SYN, and /C will be decoded as the ASCII character #.
Character pairs /M and /N decode as a minus sign and period
respectively. Character pairs /P through /Y decode as 0 through 9.
