It's hard to know exactly what's going on without sufficient "evidence".
I was feeling a bit lame - not enough energy after work to do something
that requires my brain to be turned on - so I tried to hack up an
example. Its source is attached.
I can compile it with :
arm-wince-mingw32ce-gcc -o echo.exe echo.c -lws2
You'll need to change the IP address in the source for it to work with
your environment.
Let me know if this still doesn't work for you.
