I have an external device which can connect over GPRS to the Internet using a SIM card and I want to see what data it sends. I can program it to use my computer as a server and then use a program to read what it sends. The problem is that I don't know what program to use to read the incoming data. Any ideas?
Device on the Internet > My home router > Port forwarding > My computer
I tried Windows 7 Telnet Server but I can't read what is coming.

I think Wireshark is the most common tool for inspecting network traffic. It would also allow filtering data from a specific port.
