This virtual COM port driver is designed to work the same as most serial cash drawers so that drivers for a serial cash drawer should work if mapped to the correct COM port, normally COM5 in the 650 system.

The cash drawer can directly be accessed through two I/O ports, 280 hex and 281 hex. Port 280 hex is an output only port and fires the cash drawer when toggled.

Port 281 hex is and input only port and read the status of the cash drawer.
