I am trying to write a simple smart device TCP/IP client using the .NET Compact Framework. All I want to do is open a socket, send some text and close the socket. Whenever I try to establish the connection, I get the "unreachable host" error. Do I need to set up my Pocket PC emulator to do this? How do I do this. All the docs that I've read on how to do this has not solved this problem for me. Thanks. Also, the same app works fine from my PC, it just won't work from the Pocket PC emulator.
