HELP: Open COM PORT , now how do I close com port?

[ndondo]

Hi Guys
I was playing with the tutorial bellow


http://www.devx.com/vb2themax/Tip/18343

Now the com port check always says port is not available

Is there a way to close the com port?

Thank you

[ndondo]

To add more info if I run

MSComm1.PortOpen = False

in the immediate window I get this

"DEVICE is not OPEN"

and if I run

MSComm1.PortOpen = TRUE

in the immediate window I get

"PORT already OPEN"

Then I read this article from Microsoft
http://support.microsoft.com/kb/77563

it says that beside restarting there are ways to program to reset com port
any one know how to do it?

I also tried to find freeware that will reset com port - still to no available.

I don't want to reset, because this happens quite often at our client site, and it is not look very good when we tell them to reboot the computer every time this happen

thank you
