I am trying to get and set the scan tone for my barcode scanner in VB.NET. I am able to open my scanner and get its ID without a problem but when I try to use execCommand() it fails and returns a status of 113. I get the same result for both getting and setting an attribute. This is my code for getting an attribute, my code for setting is very similar.
My company is writing application for customer, that allows him to scan his goods using Zebra DS3608 scanner. Barcode is a 3 multinumber fields separated by Group Separator signs. My software replaces GS signs with ';' in Swing KeyListener and extract this data later in the process.
I have discovered issues when using this scanner. It is connected to Win10 PC through USB as HID device. When i am scanning into my application sometimes there are some random ASCII characters instead of GS sign (○, ↔, ˘) which causes error in my process.
