To clarify a few points,
PuTTY [1] is a free telnet/ssh client for Windows (32bit).

You tcpdumps were too terse to give me a clue to figure out the
problem. Without even the SYN, ACK, FIN, RST it is hard to tell
what is happening, and it would nice to see the data payload.
'tcpdump -Xn -i eth1' would easiler to see what is going on.
What is the network layout? Are all the machines we are interested in
on a LAN (private IP address 192.168.x.x and 44.16.2.x), off either
a hub or switch? No routers, firewalls, cable/DSL modems?
Internet<--->modem<--->firewall/router/gateway

Windows TNOS
My first guess is that you have something configured wrong with
your PuTTY configuration for the TNOS machine. Check every option
for your TNOS settings.
