RS232 Communication for Inficon Leak checker UL3000

[rosh]

I am attempting to replicate in LabVIEW what I previously accomplished using HyperTerminal. Despite trying various syntax for the same commands in LabVIEW, none have been successful.

In your settings for the port, you show settings for "COM3". In the LabVIEW code, it is set to "COM1".

What happens when you select COM3 on LabVIEW?

The COM3 screenshot was actually taken from another computer. This computer I am working on now has only COM1 port.

Have you been successful with HyperTerminal on the specific computer and port that you are using with LabVIEW right now?

I originally didn't mention it as a possibility, but another thing that can cause framing errors is bad hardware.  Either a bad serial adapter or a bad cable.  It's rare but not unheard of.  If you only got HyperTerminal to work on a different set of hardware, then it remains a possibility that you're using all the correct settings but instead you have bad hardware.

I was using trial version of Hyperterminal program and it expired after 24 hours. Now I can't communicate with the UL3000 at all. With Labview, I can communicate with other rs232 devices using the same computer and the same cable.

There is also free terminal software available. No need to use a software with a 24h trial period…
