Search for the letters “FGH” in bar codes and send all the data that fol-
lows, including “FGH.” Using the bar code above:
Command string: B00003464748F10D
B0 is the “Search forward for a string” command
0003 is the string length (3 characters)
46 is the hex value for “F”
47 is the hex value for “G”
48 is the hex value for “H”
F1 is the “Send all characters” command
0D is the hex value for a CR
The data is output as: FGHIJ
<CR>
Search backward for a string
B1 Search backward for “s” string from the current cursor position, leaving
cursor pointing to “s” string. Syntax = B1nnnnS 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, B1000454657374 will
search backward for the first occurrence of the 4 character string “Test.”
Refer to the ASCII Conversion Chart, beginning on page A-3 for
decimal, hex and character codes.
Search forward for a non-matching character
E6 Search the input message forward for the first non-“xx” character from
the current cursor position, leaving the cursor pointing to the non-“xx”
character.
Syntax = E6xx
where xx stands for the search character’s
hex value for its ASCII code. Refer to the ASCII Conversion Chart,
beginning on page A-3 for decimal, hex and character codes.
E6 Example: Remove zeroes at the beginning of bar code data
This example shows a bar code that has been zero filled. You may
want to ignore the zeroes and send all the data that follows. E6
searches forward for the first character that is not zero, then sends all
the data after, followed by a carriage return. Using the bar code
above:
Command string: E630F10D
E6 is the “Search forward for a non-matching character” command
30 is the hex value for 0
F1 is the “Send all characters” command
0D is the hex value for a CR
