Honeywell Xenon 1900 User Manual page 172

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
E4 is the "Replace characters" command
02 is the total count of characters to be replaced, plus the replacement
characters (0 is replaced by CR, so total characters = 2)
30 is the hex value for 0
0D is the hex value for a CR (the character that will replace the 0)
F1 is the "Send all characters" command
0D is the hex value for a CR
The data is output as: 1234
5678
ABC
<CR>
Stop replacing characters
E5 Terminates character replacement. Syntax = E5.
Compare characters
FE Compare the character in the current cursor position to the character
"xx." If characters 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
page A-4 for decimal, hex and character codes.
Compare string
B2 Compare the string in the input message to the string "s." If the strings
are equal, move the cursor forward past the end of the string. Syntax
= B2nnnnS where nnnn is the string length (up to 9999), and S consists
of the ASCII hex value of each character in the match string. For
example, B2000454657374 will compare the string at the current
cursor position with the 4 character string "Test."
Refer to the
page A-4 for decimal, hex and character codes.
Check for a number
EC Check to make sure there is an ASCII number at the current cursor
position. The format is aborted if the character is not numeric.
EC Example: Only output the data if the bar code begins with a
number
If you will only accept data from bar codes that begin with a number,
you can use EC to check for the number.
