    Well the exception says it all. There is not such port it can access.

    I saw the code of the link u posted. It tries to connect on COM2. Is that where the device is sitting? If it’s sitting on COM1 change your code.

    Another reason would be the JavaComm installation. Have you included everything? DLLs, JARs etc? If it was a DLL issue you would get the UnsatisfiedLinkError exception too but anyway.
