greg zakharov Гулял вчера весь вечер, много нашел полезного и бесполезного. Среди всего прочего, вот:

Как воспользоваться этим? Я так понимаю нужно вызвать функцию ReadURI (не могу только понять с какими параметрами) и она вернет мне ручное управление сокетом. Хотелось бы ip:port. Если кто сталкивался подскажите, с меня 3 литра пива, темного.
