Port currently owned by unknown windows application

Hello,

Let me explain the situation in the shortest way possible:

I have a Java program that is supposed to recover from a bar code reader the value of the barcode read.

The bar code reader is connected via a serial port.

However, when I launch the application, the program raises this exception:
"Port currently owned by unknown windows application ".

But even when I remove the bar code reader, the same exception is raised.

My question is simple:

I want to know the COM1 port using by which application and how to unregistered it?

Thank you.

Normally COM ports are being used by modems. It is possible there's a conflict with your modem and the port you're trying to use for your program.

Try disabling your modem under Hardware Devices, and try again.
