In the US there is a company giving away a little barcode scanner called the
CueCat. It plugs in in serial with the keyboard and puts it's info into the
keyboard queue. I've tested it with the standard QL with the Keyboard-90
interface and it works. A test is to open a text editor, scan a barcode, and
some garbled text will appear in the editor (it's encrypted so only the CueCat
software can use it, but the encryption has been broken).
On the Q40 I have some problems. Under SMSQ/E, I get nothing in the text
editor and soon the keyboard locks up. Under Linux (ussing vi), I get the
phrase "unknown scancode 0" over and over again (looping). I have to unplug
the keyboard (and CueCat) to get the keyboard back again.
I'm guessing there is some hardware incompatability existing between the CueCat
and the Q40. I've found some info on the web on the "unknown scancode" under
Linux, but it mentioned getting two number after the text. Anybody know more
about this "unknown scancode" and Q40/Linux?
