I haven't done 2D barcodes, but traditional ones are easy. Just make
sure the scanner can operate in keyboard-wedge mode and it will act
like a keyboard. You will need to test it to see what terminating
character it sends and then check for that and when it arrives,
operate on the complete code.

I have a barcode reader test stack on my web site
as well as a stack to generate Code 128 barcodes
<>, which needs a Code128
font to display them correctly.
