Доброго времени суток. Моя проблема заключается в том, что я никак не могу грамотно и без багов в роботе соединить в одном скрипте функции посылки данных через TCP и принятия. Вот мой код. Прошу опытных программистов исправить мои ошибки и написать в чём они заключаются. Заранее премного благодарен.
