The way it is quoted, portSerial is never initialized, so CreateFile 
will receive some garbage characters as the device name to open.

Apart from that, like Robin said you cannot use a blocking call in 
idle() since it will stall the viewer. Either use overlapped I/O or 
create a different thread.

What do you want to use this for?
