A quick method for testing data transmission is to open the file corresponding to your device with the "cat" utility, then scanning some barcodes. For example, if your 1D scanner is the only USB-VCP device on the system, it can be accessed by typing "cat /dev/ttyUSB0" into the terminal. Depending on your level of permissions, you may need to be root to do this. |
