Hello,
I'm trying to access barcodes scanned and saved in a scanner's flash
memory. The scanner, Opticon's OPN 2001, connects via a USB cable
(which rather niftily also charges its battery), but the interface is
actually serial rather than "native" USB. Opticon scanners seem to be
supported as of Linux kernel 2.6.29
(http://kernelnewbies.org/Linux_2_6_29) , as in the usbserial module
is loaded and prints:
[? 196.495094] USB Serial support registered for opticon
[? 196.495135] opticon 4-1:1.0: opticon converter detected
[? 196.495529] usb 4-1: opticon converter now attached to ttyUSB0
[? 196.495557] usbcore: registered new interface driver opticon
lsusb gives:
Bus 004 Device 002: ID 065a:0009 Optoelectronics Co., Ltd
How do I access the scanned data? Presumably, an application has to
use /dev/ttyUSB0 to do so. Are there generic Linux apps. which will do
so?
Googling has not yielded results beyond the kernel version. As I have
only used the serial port for modems, I'm unsure how to proceed.
Regards,
Sameer

In MS Windows, the Opticon driver has to be configured to point to one
of COM1-3. It then slurps the data into a default file containing the
barcode, the type of barcode format, and a timestamp. There is also a
settings option to configure the scanner (turn off timestamps, e.g.).
