Hello,
I could not find any example Serial and/or File I/O examples on the NI website that go as far back as LabVIEW 3.x. However, I noticed that LabVIEW 3.x has all the standard functions for Serial I/O and File I/O. You would want to use the sequence of Serial Port Init >> Serial Port Write >> Serial Port Read to get the data from your Serial Port, then you would use the sequence Open/Create/Replace File >> Write File >> Close File for saving the data. There are examples that ship with LabVIEW 3.x that demonstrate these programming techniques...you can look in the /LabVIEW/Examples/INSTR/SMPLSERL.LLB for Serial Examples and /LabVIEW/Examples/FILE/SMPLFILE.LLB for File I/O examples.
Also, make sure to check out http://www.ni.com/labview to learn about LabVIEW 6,
the latest version of LabVIEW. An upgrade to this version would only be $395 if you are a registered LabVIEW user!
Have a great day,
