Need resolution wrt OPOS driver

When DS-9808 scanner set to OPOS driver mode, is there any settings to apply onto scanner, including function key mapping?’

 

At one of the customer site, they have created a QR code with multiple EAN barcodes separated by CR+LF as a function key. Scanner supports it only in normal USB host mode but as soon  we program it for OPoS then the same doesnt work.

 

has anyone tried this anywhere?
