C,C++ or JAVA APIs or libraries

I was wonderring if you could recommend any C++ or JAVA tutorials, APIs or DLLs to easily send data accross the serial port to your products.

Also is there a program that you can download to just send data across the serial port just for testing? Like send 0x80 , 0x52 … then see what happens. I would rather avoid basic stamp.

I found this after searching around through old , old code out there. This worked to get my Pololu Motor Controller running:
