I wonder when I write this code:

mscomm1.OpenPort=True

I connect Computer to standard phone(device) already. And it always show error like this Port already open. It has problem with code ,problem with Connector or problem with device(standard phone).

                                  Please i need answer.Please help me!

It is good if i call u by ur name.

Anyway the error u getting because of some reason. The reason is the port u r trying is used by another application. And be aware about use END to program instead of Unload the Form.

And if u still persist the problem better u put ur code of communication.

Goodluck.
