I have a telnet connection through askubuntu.com 80 while trying to test cli based webbrowsing for github project. I got my connection established over port 80 but now I cannot do anything, even quit. Is there a way to quit this kind of connection? `CTRL`+`c` is not working and neither is any other key combination.

Closing the tab may be the answer but this is not I want because I am planning to run a script over telnet and I do not want to install any browser like lynx or anything else. I want to use only the default programs we have in Ubuntu.
