| the barcode scanners we use just produce a 9600 baud serial stream.

The PS/2 and USB versions I've used appear as a keyboard and just "key in"
the data like a keyboard.  To get data from the USB I just did a
"cat /dev/ukbd0" for scans.  They've had built-in wdges.  Makes it
really easy to integrate into systems.
