3.2.Code 39

This is the most popular alpha-numeric bar code symbology. It has a set of 43 characters (alphanumeric and a few symbols) and can be used with or without a check digit.

3.2.1.Standard/Full ASCII

The Code 39 Full ASCII option allows the transmission of the 128 ASCII characters. Each ASCII character is a combination of two Code 39 characters. It can be very useful specially to transmit control characters (STX, ETX, TAB, EOT…) as preambles or postambles in a message (see appendix 6.3, page 58). The Code 39 Full ASCII Table is listed in appendix 6.10, page 70.
