If the bar code has characters that the host application does not want included,
you can use the E4 command to replace those characters with something else. In
this example, you will replace the zeroes in the bar code above with carriage
returns.
Command string: E402300DF10D
The data is output as:
1234
5678
ABC
<CR>
E5—Stop replacing characters
Terminates character replacement. Syntax = E5.
FE—Compare characters
Compare the character in the current cursor position to the character “xx.” If char-
acters are equal, move the cursor forward one position. Syntax = FExx where xx
stands for the comparison character’s hex value for its ASCII code.
Refer to the ASCII Conversion Chart (Code Page 1252), beginning on page 174 for
decimal, hex and character codes.
EC—Check for a number
Check to make sure there is an ASCII number at the current cursor position. The
format is aborted if the character is not numeric.
Example: Only output the data if the bar code begins with a number
If you want only data from bar codes that begin with a number, you can use EC to
check for the number.
