Re: UPC or Barcode Scanners

[Ray Bennett]

I use a WASP USB barcode scanner in a HyperCard application that I'm porting to Rev. Haven't ported it yet, but see no reason it _shouldn't_ be straightforward. The trick is that the scanner is programmable. Meaning that you can program it to send a preamble (read, "handler name") when it reads a code. For me, I just named the preamble "wasp".
Then, in my Home stack (main stack in Rev), I have the handler "on wasp barcode".
When you "gun" a code, the barcode reader sends keyboard input that looks like this:
wasp "Francis Bacon 125"

I put the "on wasp" handler at the top of the hierarchy so that all of my substacks could avail themselves of it.
Hope this helps.

Has anyone used Revolution to capture input from barcode readers/scanners
connected via serial or USB? I have tried without success. The unit beeps,
telling me the UPC is valid, but I get no text in my field. I have tried
the examples on opening and reading from serial ports in the Rev help. I
also tried the TEST SERIAL Rev app that was provided here on the list
several months ago. Is there a preferred type or brand of UPC scanner that
works best with Rev? Is there some sample scripts available that does this
sort of thing that I could use as a guide/tutorial?
