Intermec barcode scanner returns CTRL-J when scanning

I have plugged in an intermec bardoce scanner into my lapto to check out a barcode scanning application. I scan the required fired, the scanner bleeps and returns the scanned data terminated by CTRL-J. This means that the favorites box is opened every time in internet explorer. In Firefox, it is the download list. How can I get round this problem?

A couple of options here. The simplest would be to look at the scanner and see if can be configured to send another character other than CTRL-J (ENTER for example) at the end of the scanned data. I would expect this could be changed.
The second option would be to add some JavaScript code to trap the keyboard event so the CTRL-J would be ignored.
I could provide a js code snippet to help here but I would try the scanner configuration first.

here is some code to trap CTRL J
Code: Select all
document.onkeypress=function(e){
var e=window.event || e
if (e.charCode && ( e.charCode==106 || e.charCode==74) && e.ctrlKey)
return false;
return true;
}
