The 80 hex will be replaced by a single character
identifying the decoded barcode symbology.
See the Symbology Chart, above.
The 81 hex will be replaced by a three character string:
]CM
Where: ] is the symbology ID flag character
C is the symbology ID character
M is the modifier character
See AIM Guidelines on Symbology Identifiers for
more information.
When placed at the end of a transmitted message, the
LRC checksum provides a modest amount of error
detection. The checksum is computed as the
Exclusive-Or of every transmitted character, after being
initialized to zero.
The LRC checksum can have any value 00 through FF
hexadecimal, but not all characters in this range are
printable. This option causes the LRC checksum to be
transmitted as three characters; two hexadecimal
numbers plus a space.
A single character is transmitted having a value 00 through
FF hexadecimal.
For initializing the checksum to some value other than
zero, XX can be any value 00 through FF hexadecimal.
This option is set as the first prefix.
