Hi All,

I am writing an application which will trace all chat of employees using any chat facility like gmail, yahoo etc.

I am thinking is it possible to capture a message from serial port.

Anyone have knowledge regarding this so that you can help me with any example.

Thanks

You can check to see if a port is being used by using SerialPort.GetPortNames Method.

Once a port is opened you cannot monitor the activity on a serial port, unless you are using a hardware device.

You can use Portmon from Sysinternals to monitor serial port activity but you need to know which port is going to be used beforehand.

Thanks Sergey.

I did wonder what the OPs intent was.

Well, you could capture a message going over a serial port, but that's not going to do you any good at all capturing something that never touches a serial port.

You cannot do what you want. Why? Because the chat seesions over GMail, Yahoo IM, and many others are all encrypted. You cannot see what's inside those encrypted conversations.
