E6 Example: Remove zeros at the beginning of barcode data
This example shows a barcode that has been zero filled. You may want to ignore
the zeros 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 barcode 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
The data is output as:
37692
<CR>
