Remarks
The cash drawer device supports a command to “open” the cash drawer.
The cash drawer may have the following additional capabilities:
Drawer status reporting: Can determine whether a particular drawer is open or closed in environments where the drawer is the only drawer accessible via a hardware port.
Drawer unique status reporting: Can determine whether a particular drawer is open or closed in environments where more than one drawer is accessible via the same hardware port.
The cash drawer is a sharable device. Its device sharing rules are:
After opening and enabling the device, the application may access all properties and methods and will receive status update events.
If more than one application has opened and enabled the device, all applications may access its properties and methods. Status update events are fired to all of the applications.
If one application claims the cash drawer, then only that application may call the OpenDrawer and WaitForDrawerClose methods. This feature provides a degree of security, because these methods may effectively be restricted to the main application if that application claims the device at startup.
