Open a till draw

[mswilson16]

I have recently designed a stock control system in Access 2k. The actual system is running fine but my boss has said that it needs to open the till and also trigger a electronic stand alone timer.

I have heard people talking about getting the computer to open a till but I haven't got a clue how to start the timer running!

Any help what so ever will be great ESPCIALLY on the timer one.

First, the till drawer.

Usually this will be done via a serial port. You would open the port, say COM1, and write a string to the port.

You will need to know the communication parameters required by the till; data bits, stop bit, speed and parity if my memory is correct.

Look at OPEN COMx in the help and you should see some examples.

I suspect that triggering the electronic timer will be achieved in much the same way. You would connect it serially, open the port for output and write to it.

The manuals for these devices will have a precise description of how you go about connecting to them and what is to be sent to trigger activity.

Hth,
