Is there any standard utility for opening a connection to a TCP/IP port and then interactively sending data and seeing responses? For example, I'd like to be able to open a connection to port 80 on some machine, type "GET / HTTP/1.0" and then see the response. I'm experimenting with some protocols, and this sort of thing would be helpful. I think I could probably write something like this, but I was wondering if it already exists. Thanks, Kris
