Entering control characters in barcode generator

[TNguyen]

I am working on a project similar to your online barcode generator. I need to have control characters like GS, RS and EOT received from the web form. Is it possible? I can't enter these characters at your site.

It is not possible to pass control characters verbatim to the server using a HTML form. They are stripped according to HTML spec. You can use the tilde codes to pass those characters, as described in the manual:

Note: tildes vary from symbology to symbology. The above link lists the ones supported in Code128.
