UPC
Universal Product Code
A 12-digit bar code pattern adopted by the U.S. grocery industry. Encodes the
number system character (type of encoded product), five-digit manufacturer
number assigned by the UPCC, five-digit product code assigned by the
manufacturer, and a modulus 10 check digit as the 11th character. The code is
numeric, and there are other versions. Nominal dimensions for the UPC
symbol include a module width of 13 mils (+-) 4 mils. Magnification factors
range from 0.80 to 2.00 of nominal supporting densities of 10.21 to 4.08
characters per inch, with a nominal of 8.17 characters per inch.
User-Defined protocol
A custom protocol that can be modified to meet specific host requirements.
Version A
Standard 12-digit UPC Symbol.
Version E
Special 6-digit shortened UPC code that requires less space and uses zero
suppression.

Enables or disables XON/XOFF flow control and defines a character that reenables
transmission when the device can receive data again after an XOFF. 1
