If the 'OPOS' option was selected in the Drawer field,
you must enter the OPOS driver name for the drawer here.
Both the Programmatic ID and the Logical Device Name can be used as the Device Name for the drawer.
You can find the Programmatic ID and the Logical Device Name in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\OLEforRetail\ServiceOPOS\CashDrawer.
