Hi,
There's a KnowledgeBase entry on using XModem file transfers in CVI, and it is very useful.

This is valid for your version of CVI. I hope this helps you with any problems you may have, good luck!
NOTE: For more information on CVI's XModem functions, the LabWindows/CVI Help that is installed with CVI is a great help.
