Hello
Check out the libraries for RS-232 installed with CVI. You can also use the visa libraries to communcate with these ports. These functions include the documentation that you can access by right-clicking on the function panel.
If you need examples, check out the
Serial Instrument Connectivity page. You can application notes and examples about using the serial ports.
I hope this helps
