Hi! 1) Open command prompt -> 2) type "telnet" -> 3) type "open httpbin.org 80" (make sure to type the word "open"). After that your GET command or whatever you type will show in the top left corner, overwriting text that's already there. If it does not work then type "set localecho" between steps 2) and 3).

Hi Darko,

I was having the same problem and eventually tried enough combinations and it worked. Jennifer and Konstantin are correct (kudos to them for coming up with the solution!).

After entering "telnet" in the console type the 'set localecho' command as the other posters suggested.

set localecho

This command will cause the text you type to appear in the upper left corner of the screen (over top of text already in the console window - makes the text difficult to read...). Once you get to this stage type the commands as shown in the video:

GET / HTTP/1.1
Host: httpbin.org

Hit 'enter' twice after the last command and you should get the result as shown in the video

Take a look at this from Microsoft. I still feel like the answer lies in the localecho which is shown under the display command. https://technet.microsoft.com/en-us/library/c.aspx

Solution #1: open command promt as admin (right click on the icon -> launch as admin). It will work and connection won't be lost. After that every other session will work too, so you don't have to launch it as admin everytime. Solution #2: just type "telnet httpbin.org 80". It won't display what you type but connection will be stable.
