There is no way that anyone can answer such a vague question. You'll need to give a lot more information about the problem and the steps you have already taken to solve it.

What sort of display? How does the display connect to the main system? What programming interface does it have?

From that general product specification I am guessing that you are wanting to send your display to the: VFD Customer Display for Cashiers part of the system - either the VFD-890 or VFD-895
Unfortunately it is not clear how that device attaches to the over-all POS system and it is not defined in the device's specification.
The over-all device lists the following as Interfaces
We can guess that the small display uses a USB port, but YOU have to make sure for us and then let us know.
Instead of us having to guess, maybe YOU should look at the equipment that your Boss has or contact the vendor or manufacturer and get it clarified so that we can help you.
Good Luck,

The over-all device lists the following as Interfaces
* 1 x DB25 Parallel Port (most likely for the Printer)
* 6 x USB 2.0 (External), 2 x USB 2.0 (Internal, 1 reserved for touch screen)
* 1 x DB-15, VGA Port (most likely for the Monitor)
We can guess that the small display uses a USB port, but YOU have to make sure for us and then let us know.

Hi mouradoualha,
I am controlling an Epson DM-D110 POS Display from my Visual Foxpro App. Just do the following:
1) Install the driver for Your POS Display
2) Send the required string directly to Your POS Display:

Hi,
if You have connected a cash drawer to Your POS printer, You can also open the cash drawer programmatically from Your Visual Foxpro App. Just do the following:
1) Install the driver for Your POS printer
2) Send the following string directly to Your POS printer:

That is some good advice, but it is dependent on the devices having already been INSTALLED as 'printers' into the Windows OS of the POS workstation.
mouradoualha has not yet informed us if that is the situation or not.

Have you thought of asking your boss if he knows how to do it? Or how you can find out to do it? After all, it is your employers that purchased and installed the device. They should at least know where to look for the technical information.

He doesn't need to be a programmer to know where to find the device's documentation, or how to contact the vendor.

Hi mouradoualha,
having Your POS display related to a COM port is also no problem! Just do the following:
1) put a Mscomm32.ocx ActiveX Control on a Form
We assume that the instance of Your Mscomm32.ocx ActiveX Control will be named OleControl1 (otherwise adjust this name)
2) put the following code into the Form Init Event:
3) put the following code into the Form Destroy Event:
4) Send the required string via COM port to Your POS Display:
