message if any are necessary. Each entry is unique to the
previously specified Bar-Code Type. Scan the Hex 0 tag for
no Common Bytes, Hex 1 tag for Common Byte 1, Hex 2 tag
for Common Byte 2, or Hex 3 tag for Both Common Bytes.
The default for this parameter uses Common Byte 2 as a
suffix for Code 128, and Interleaved 2 of 5 bar code data.
UPC and EAN bar codes do not use Common Bytes.
Permits you to specify the data sent to the host terminal or PC
in the Unique Identifier field. Each entry is unique to the
previously specified Bar-Code Type. Input this information as
two Hex characters for each Common Byte and use Hex

Appendix A). Do not use the same characters as the
Terminator Byte because the message will terminate too soon.
