Hi

I'm using MATLAB to connect with serial port.

I wanted to disconnect serial port when my code ends with error, and i tried many ways but those didn't work at all.

There are some problems.

MATLAB memory holds connection with serial port when code ends unsuccesfully.
When I try to connect with the port, I fail to connect with seiral port because MATLAB still holds serial port.
The object which I used to connect with port dosen't exist when code ends.
Moreover, I'm using additional '.dll' file so fclose() command dosen't work.

So I'm asking if there is any way to disconnect the serial port?

I know the name of the port, so I want to disconnect the serial port by using its name.

Thanks
