RS232 Pins

Recommended Posts

Does anyone know if it is possible to get LabView (ver 7.0) to look at the individual RS232 pins. I am wanting to detect a switch operation without the use of a DAQ card by monitoring the RTS or CTS line. I am not sending or receiving specific bytes of information. Just wanting to detect a voltage. Any assistance will be gratefully appreciated.

I needed to do this for a UI device that I built a tester for.

the test code didn't use hardware hand shake lines but the customer application did.

I found that if you use a property node on a serial visa reference it will give you control of the hardware lines.
