+       exchange TCP packets.  Basic instructions:
+
+       On the server node:
+
+         nsh> ifconfig wpan0
+         nsh> tcpserver &
+
+       The ifconfig command will show the IP address of the server.  Then on

+
+         nsh> tcpclient <server-ip> &
+
+       Where <server-ip> is the IP address of the server that you got above.
+       NOTE: There is no way to stop the UDP test once it has been started
+       other than by resetting the board.
+
+       Cheat Sheet.  Here is a concise summary of all all the steps needed to
