You actually really are connected to Bing.com over port 80. Notice that your cursor is now at the top leftmost character space. If you start typing, you'll move the cursor and start typing over existing characters. Try that again, but use the following:
Start > run > telnet
o thenubbyadmin.com 80
You will then see the seemingly neverending "Connecting to thenubbyadmin.com..." Next type:
GET / HTTP/1.1 [return]
Host: thenubbyadmin.com [double return]
Yes, that's my website. No, I'm not trying to pimp it. It's just that's what I'm certain will work since I was playing around with web browsing in telnet just a few days ago using my own site.
Why does Window's telnet work that way? What's with the funky way it positions the cursor depending on how you launch telnet? I don't know. It drives me mad. Let this be a lesson to never use Windows's built-in Telnet app and stick with PuTTY.
