Are you sure you are entering the right device name? On Linux I scan the 
/dev directory for ttyS* and ttyUSB* to see what's available as a valid 
serial port. You can do a similar thing on Windows, but it's so long 
since I had to use it I can't remember how. Once you have the valid name 
as a string you can pass that to your routine to open the port.

FWIW, I find the QExtSerialPort classes work very well.
