It may sound silly that an experienced developer cannot even come out of a telnet terminal but this is a true story. I tried every possible Linux commands I can think of which is used to close, cancel a command, or exit from VIM editor in UNIX, like Ctrl + C, quit, exit, q! and even the escape character '^]', only to realize that nothing is working. Though I have used telnet before, when I use it after a long time, I actually forgot how to close the telnet terminal and how to get out of it.
