You should be able to. The question is whether or not the vendor will tell you how.
First step is to contact the vendor and ask for a copy their documentation on how to talk to their instrument over the serial port.

As Mike said..
Also:
Do you have the developer (or API) manual? Typically, you should have a list of commands that you can send to the instrument using serial port communication software such as "HyperTerminal". If so, then you can manually try out a few commands using H-T. The use the same commands to experiment with LabView code.
If you are able to use software like HyperTerminal, then using the VISA serial communication tools will be the simple way of implementing your solution. Here are some links which may provide clues on how to proceed. You can also do a search on VISA Serial communication.

Well there you go. It looks like you basically have two options: VISA which will be more efficient but might require more code to build command strings, and the company's DDE server which is simpler to use from the LV world, but much less effiecient and would possibly impose future compatability problems--like what happes if (when?) DDE goes the way of the dinosaurs?
Then also the DDE example pretty much stinks in terms of the quality of the code...

Do a search in examples on "DDE". Also check Microsoft's website. There is a lot of info there.

Hi, did you connect a loose-end rs-232 to a digital module or did you connect rs232 to usb directly into the PC?

The original poster's last post was almost 13 years ago, so I wouldn't hold my breath for an answer.
