J2 Virtual Serial Ports Drivers
Virtual serial ports can be used for the cash drawers, virtual 2x20 line display on the
optional 10.1 LCD, Smart UPS, MSR and iButton.
To open virtual serial cash drawer send a bell character to the Com port it is assigned to.
(The bell character is the ASCII 07 hex character “Control G.”) The open/close status of
the drawer may be obtained by reading the status bits of its COM port. The drawer
open/close status will be reflected on the CTS and RI bits, either bit may be used. This
virtual COM port driver is designed to work the same as a hardware serial cash drawer
and will work with drivers for serial cash drawers.
