篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Qt实现telnet服务记录相关的知识，希望对你有一定的参考价值。
最近在做关于FlightGear的一个指令控制的研究，由于每次都需要手动从cmd跳到telnet中，所以实现拿Qt实现一个telnet功能的小模块。
目录
FlightGear(开源)
FlightGear是一款开源飞行模拟器。项目始于1997年，主要目标是为学术科研领域创造一个尖端的飞行模拟器框架，也可拓展到飞行训练，飞行仿真，模拟飞行游戏等方面。
它支持全球三维实景，20,000多个跑道、400多种飞行器、跨平台、多人联飞、多样的开放飞行数据模型等功能。重点这是开源的。

Pro配置文件
在*.pro文件中需要添加

LIBS +=-lws2_32

\\class QtTelnet
\\brief The QtTelnet class proveds an API to connect to Telnet servers,
issue commands and receive replies.
When a QtTelnet object has been created, you need to call
connectToHost() to establish a connection with a Telnet server.
When the connection is established the connected() signal is
emitted. At this point you should call login(). The
QtTelnet object will emit connectionError() if the connection
fails, and authenticationFailed() if the login() failed.
Once the connection has been successfully established and
you've logged in you can send control messages using sendControl()
and data using sendData(). Connect to the message() signal to
receive data from the Telnet server. The connection is closed with
close().
You can use your own socket if you call setSocket() before
connecting. The socket used by QtTelnet is available from
socket().
