The table below shows you how to enter non-printable ASCII control
characters (ASCII 0 through 31) into a text string. For example, to
enter carriage return and line feed control characters, enter %M%J.
The decoder interprets %M%J as the ASCII control characters CR
and LF. The % character is equivalent to ASCII 37 (decimal).
You always enter non-printable control characters as a 2 character
sequence and the second character must be listed in the following
table. To enter the % character, use %%.
