This signal will be send via RS232 to Com 1 of the PC where I've load the hyperterminal.The microcontroller and the hyperterminal are initialize on the same Baudrate and the same protocol,but the hyperterminal says nothing.Which mistake in logic have I made. Perhaps you can help me. Looking for your information Ingo Brockmann

Hyperterminal is notoriously unfriendly in such applications! A real "glass teletype" dumb terminal is your best bet (assuming that you don't have an RS232 analyser/monitor). Have you checked on an oscilloscope that you really are getting the right voltages & timings?
