<ESC>n – Is encoded as FLG(n), and is interpreted as signaling Extended Channel
Interpretation. When the value of n is from 1 to 6, it signals that the following n
digits comprise an extended channel identifier for use with ECI compliant bar code
scanners. An erroneous bar code symbol may result from failing to follow <ESC>n
with n digits. Any <ESC>0 following <ESC>n and not within the n digits will be
encoded as FLG(0). In the context of a FLG(n), any backslash '\' (92
interpreted by the scanner as two backslashes '\\'.
Example 1: The variable length example encodes "AZTEC" with no ECI input, and 23% error
correction, and prints the bar code. A line of text is also printed.

Example 2: The specified length example includes a byte count field for all bytes that follow until the
end of the bar code data. The byte count is 17. The symbology encodes
"AZTEC<CR>barcode", and prints the bar code. Notice that a <CR> does not terminate
the bar code format record. A line of text is also printed.
