Stop suppressing characters

Replace characters

command is encountered. Syntax = E4nnxx

E4 Example: Replace zeroes with CRs in bar code data
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 char-
acters = 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 ASCII Conversion Chart (Code Page 1252), beginning on page A-3 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 ASCII Conversion Chart (Code Page 1252), beginning on page A-3 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 want only data from bar codes that begin with a number, you can use EC to check for the number.
Command string: ECF10D
EC is the “Check for a number” command
F1 is the “Send all characters” command
0D is the hex value for a CR
