close multiple serial port instances

Hi All,

 

This has been annoying me for a while but I have never bothered to look into it until now!

 

I have a VI that is used fo developing tests.  I communicate with a serial device through com1.

 

The people using this VI regulary shutdown the VI without using the GUI and the shutdown button.  On the next intialise a new comport port reference is instantiated and after a while this cna grow to be quite big so that it appears a list appears in the visa control,e.g.

 

com1

com1(1)

com1(2)

com1(3)

com1(4)

 

Also, see attached screenshot.

 

VISA FIND RESOURCE only shows the aliases and not the instances.

 

Is there a way that I can look at all the open references and close them all programmatically before initiating a new reference?

 

 

Thanks,

Sean
