Cant close serial port in windows form application

[bigbrownbeaver]

The problem is when I close the port my program hangs. When I close the serial port, or the form, my program throws an exception, after hanging for a while. Basically it hangs whenever I call SerialPort.Close(); Help would be greatly appreciated :)

can you post some code? do you have any program loops reading input from the port? what is the error exception.message?

If it' stuck, DO NOT pull harder!
