I need to be able to open a cash drawer without using a printer. The cash drawer connects to a Point of Sale device via an RJ11 cable/connector.
I'm not sure the best way to create the file to send the code to send the open and close command.
Can anyone help?
The POS manufacturer's sample commands are:
Cash Drawer Controller Register
The Cash Drawer Controller use one I/O addresses to control the Cash Drawer.
Register Location: 48Ch
Attribute: Read / Write
Cash Drawer Control Command Example
Use Debug.EXE program under DOS or Windows98
Command Cash Drawer
O 48C 04 Opening
O 48C 00 Allow to close
Set the I/O address 48Ch bit2 =1 for opening Cash Drawer by “DOUT
bit0” pin control.
Set the I/O address 48Ch bit2 = 0 for allow close Cash Drawer.
