read/write to a serial com port

[calebyaj]

I  have a project that I want to program a VI in  LabVIEW to write to and read from a emulator board via the serial com port. I have looked at some of the examples in LabVIEW but that still does not help.   If anyone can lead me in the right direction or have VI's that was written for something like this, I am greatly appreciated.

Thanks,

Why don't the shipping examples help? What problems do you see when you try them? Please be specific as to error codes or any other information.

I wrote some commands (in Hex) to the emulator board. Once those commands were written, the emulator will be sending out raw data. But the VI read nothing back but  gave out the following error:  Error -1073807253 occurred at VISA Read. Possible reason(s): VISA: (Hex 0xBFFF06B) A framing error occurred during transfer.  What does this means?

See if this helps.

Yes, it was help to know, but didn't solve my problem.

I forgot to include some information. I 'm acutally using an USB port which act as a virtual com port. I don't know if this is the problem why I'm getting the error.
