Pause Script and Carriage Return

I have a file that uses a bar code scanner - It goes to the propper field and pauses the script, waiting for an entry. Here's the problem - the scanner scans the bar code, then puts a carriage return (It doesn't actually put the symbol there, but it's like you typed in the numbers and hit return instead of enter).

What should happen is after the scan FMP should resume the script. But since the enter key is not being pressed, it does not see this. I cannot reconfigure the scanners as they are also used for other apps on the side, and so far with FMP they work great except for this one thing.
