Huh?  The scanner has EIA232 output?  (sorry, when I
work with barcode scanners I am usually dealing with
"raw video"  :-/ )

tip(1) should suit you just fine.  Note that
you can tell tip(1) to capture the "output"
from your device (RTFM) if that is of any interest
(not sure if your device decodes particular
labels or just gives you "bar data")
