Проверил TestCom петлей физической и IEC Tester - работает заворот. В Hyperteminal между двумя компами текст отправлял. Но есть один момент, требующий внимания. Пока я еще не занимался настройкой размера TCP-сегмента. Он должен быть небольшим при работе с асинхронными данными, иначе большая задержка передачи будет.
C UDP не тестировал, вроде по TCP нормально работает.
