The ideal situation would be a scanner that had a wireless connection to the computer (RF, bluetooth, whatever) back to the computer, not a wired device. The barcodes being scanned won't be right next to the computer. My understanding is that USB barcode scanners can work in Wedge mode or RS232 mode. The alternative is a barcode scanner in wedge mode that can send a command sequence (Ctrl+Shift+F12+wave rubber chicken) that the window manger (sawfish currently) can be configured to grab, run a command, and pass the input string along. Monitoring RS232 and taking action that way seemed like it would reliable than intercepting key strokes or hoping that the user put the curson in the correct field. -- Andrew S.
