Transmit Symbols in Codeword Format

Parameter # Afh
Enable this to transmit each PDF symbol as directly decoded data codewords, whether or not that symbol is part of
a macro PDF sequence. Note that data is output as codeword values, not as interpreted data.
"Codeword values" is an ASCII representation of a number from 000 to 928 for each codeword, preceded by an
escape character. This escape character is a backslash by default, but you can change this value. For example,
the codeword value 005 is sent to the host in the form of \005 for GLIs, and \C005C for ECIs. This output format is
based on the AIM USA Uniform Symbology Specification for PDF417 (1994).
All output codewords are exactly 4 characters for GLIs and 6 characters for ECIs. However, there can be
non-decodable characters in the PDF symbol, such as a GLI sequence. This special codeword sequence activates
a certain kind of interpretation to the encoded data. Non-decodable codewords like GLIs are embedded in the
output stream like any other codeword, e.g., \927\001.
Because GLIs are indistinguishable from other codewords in the output data stream, the host must recognize them
as GLIs and process their interpretations.
Note that when a macro PDF sequence is transmitted, the last character in the last block of data transmitted is
always \922 (if selected). This indicates the end of that macro PDF transmission.
