"Is it possible to wirte a message to hyperterminal from my develop-kit?" Probably.
could you give me an example of some code where a string is being printed to hyper terminal?
Your dev kit knows nothing about hyperterminal - or any other sort of terminal. All it knows is that it has a serial port to which it can send characters, and from which it can receive characters. There are loads of examples for doing that!
"could you give me an example of some code where a string is being printed to hyper terminal?" printf("Hello hyperterminal\n");
