How do I receive TCP data for debugging?

Finally got my ESP8266 wifi chip working (thanks to my new logic analyzer). I know it's connecting to my router, so all seems to be working.

Here's the issue:

I want to set up a TCP connection from the chip to my computer through my wireless router, and send a hello world. Does anyone know of a simple program (for windows 7) that can listen to a port I specify and display all received data?

What do you call such a program, exactly? My first thought was sniffer, but being that it is designed to receive the data directly it sounds more like a server.

Thanks!

A TCP communication ? You mean connecting to a webserver and sniffing all trafic ?
Perhap you find this useful : Handy TCP/IP Server/Client Tools download | SourceForge.net

User SurferTim had me use the tool 'putty', I did use it with 'RAW' mode, but I don't understand it very well.

I use netcat for that, but it is a Linux utility. I don't think it is available for Windows.

You might do a Google search to see if there is a program available like it for Windows.

edit: netcat is available for Windows according to a Google search, but I can't recommend one version over another.

I use it like this. It is command line, so from a command prompt:

nc -l -p 80 -v

Just got ncat(netcat replacement) for windows, and it seems to be exactly what I need.

For anyone who finds this in the future, the command to just listen is ncat -l . So "ncat -l localhost 8080" for example.

This one ? Ncat - Netcat for the 21st Century

If SimbaSpirit doesn't verify it, just a quick look at the man page says that version would work.
