Pos application

[mastrob]

I am writing a pos application and need a few syntaxes

First i want to be able to write to a cutomer pole display by using vba in access 2000.The pole display is coonected to the com 2 port and has a baudrate of 9600 .
In my application , whenever the user select item the price must appear on the pole display. I know how only that somehow i need to print to this device.
Can anybody help me please ?

Problem 2
For this same application i need to open a cash drawer whenever a receipt is printed. i looked this up in the manual of the pos printer(epsom tmu210 d).There it is said that you must send a pulse to the printer. The cashdrawer as you know is connected to the printer.
The manual says to use the following syntax in dos.
printer.print chr$(130)
I typed this exactly in the command promt of my windows nt machine. but this does not work.
I can use the shell command in acess 2000 to open any external program so i thought i could write the statement in DOS and call it from access.
Can somebody also help me with this ?

Problem 3
Is there any way by which one can know when the cash drawer is open or close in access 2000

Thanks in advance
