Question Putty RAW mode connection

I am trying to use Putty to make simple point to point connection between two machines that I control. The idea is to debug and verify some basic networking stuff so I can do some fancier things later.

I wish to open a putty terminal on each machine and be able to type on one console and see my input on the other terminal. That's it. Should be easy. And I want it to happen over TCPIP. These machine are connected through a hub (not a gateway) and can ping one another , although they don't know each other's name.

I have gone into the firewall and opened port 1950 on both boxes.

On each box, I configured a putty connection as follows:
- RAW mode
- IP addy of other machine
- Port 1950

I fire up the connection at either end, type madly .. nothing. Eventually the connection times out and I drop.

I have accidentally connected to an active port (80) and seen junk on the screen, so I know that much is working.

I also have experience with Putty as an ssh client so I know basic putty moves.

Do I need two port numbers? What is going on?

As I understand it, Putty is a TCP client application, and it expects to communicate with a server. Having two client applications to establish a TCP connection will never work. You connected to a server on port 80; almost certainly a web server. In order to communicate, you will need one host to run a server that listens for connections from a calling client.

In addition the netcat tool would be a better choice. It is available for both linux and windows.
