I am trying to write, then read from a serial port using commport.dll. I have a .vi that somebody wrote that works for write. When I copy and paste the write string function, and then change it to read a string, I get a cryptic note about not changing the primite - I don't know what that means. When I run the .vi, it crashes labview. So I can't do any troubleshooting. Context help is useless. Error messages cryptic and non-explanatory. How do I do this using commport.dll????

LabVIEW

The workaround described recomends using the VISA Flush Buffer after a VISA Open. It would look like the image below.
