Hi thanks. But the hyperterminal program is closed, meaning that the serial port is now closed.
There are no other programs using the serial ports
How do I find out if one or all the serial port is busy?

What is the actual error number that is being generated? That's an important piece of information you need to provide. Also, attach a picture or the VI with the actual settings you're using. If you post a VI, if you're using front panel controls to set the parameters, be sure to first select Operate>Make Current Values Default and then save it. There's an awful lot of possible causes for an error and the more information you provide, the quicker a solution can be found.

Is "resource name" control pointing to an available port on your machine? Try opening the port on wich "visa conf. ser port" hung in hyperterminal to see if it is busy or not. Also, try telling the program to continue on the error pop-up dialog, to see if execution will continue normally.
Yes, you do need the NI-VISA driver. The page is linked below with a KnowledgeBase about that specific error you are getting. I hope this helps! Have a great day!
