em-simple_telnet.rb 오류 'pause_and_wait_for_result'

Question

MUD client으로 텔넷을 사용하고 있습니다.

날씨가 like Apache does인데이 오류는 아마도 em-simple_telnet API을 올바르게 사용하지 않는 것으로 보입니다.

Answer 1

좋아, 내가 첫 번째 링크를 참조하십시오. 그것은 말한다 : 그것은 MUD에서 어떤 반응을하지 않는 경우

A MUD client is a computer application used to connect to a MUD, a type of multiplayer online game. Generally, a MUD client is a very basic telnet client that lacks VT100 terminal emulation and the capability to perform telnet negotiations.

불행하게도, 나는 그 시간을 텔넷 보석 텔넷 협상을하려고 생각하고. 텔넷 프로토콜을 따르지 않는 텔넷 클라이언트가 무엇을 의미하는지 확신 할 수 없습니다.

소켓이있는 MUD 서버에 연결해보십시오.

Answer 2

em-simple_telnet의 readme에있는 예제를보십시오. EventMachine.run (...) 호출로 감싸 야합니다.

또한 "호스트"및 "포트"대신에 host 및 : port와 같은 키를 사용하십시오.

end 

제대로 API를 사용하지 않았다 실현하지 않았다.
