[Twisted-Python] Simple Telnet Client - couldn't get answer form server

I try to get from standard telnet server answer. I connect to this server, and now dataReceived() should give me a full answer from server like: Ret Hat Linux relase: ... login:, but it does not. I would like to know how to connect to this server and grab this data. dataReceived gives me something like that: #' (translation in telnet codes: IAC DO TERMINAL_TYPE IAC DO SPEED IAC DO X_DISPALY_LOCATION IAC DO NEW_ENVI_OPTION ((hex)FF FD 18 FF FD 20 FF FD 23 FF FD 27)). What should I do with this. I try to transport a answers for this questions. Maybe i got a mistake in code, somthing i do in wrong way? Code I working on in attachment.
