Close HyperTerminal Application using LabVIEW

[Ray.R]

I have a client who wants LabVIEW to close the HyperTerminal Application automatically is it has the serial port open.

Detecting that the serial port is already in use is simple.  I already have a popup that tells the operator to close any communication application because the port is already in use; however, they want it done automatically.

HyperTerminal does not have ActiveX support and they will not go to the more professional version which does.

A long time ago, I had read a thread where it was possible to close (or open?) and application that did not have ActiveX support.  I was hoping to use this similar approach..  Opening the app is simpler, but closing it is a different story.  You need some sort of reference to that application to tell Windows which one to close.  The OS in Win-XP.

Suggestions are welcomed.

OR

Taskkill  (command line as well)  http://technet.microsoft.com/en-us/library/bb491009.aspx

taskkill /IM hyperterm.exe

will kill all hyperterm windows open, BUT it will ask you if you want to close any open sessions, which I think you don't want. 

taskkill /F /IM hyperterm.exe

does the trick (without chewing up the com port, I just tried)

Thanks Britoa,

That was it.  I couldn't remember the name "taskkill".
