+/* CyaSSL example client
+
+This example uses a static IP Address of 192.168.2.4
+Change that in the eth variable if yours is different
+
+If you're using dhcp uncomment the dhcp line and comment out the static ip
+
+This example assumes the SSL server is at 10.0.1.2 on port 11111
+Change those in the main loop if yours is differnt
+
+The example connects and then writes "secure hello from mbed" to server
+Any repsonse will written to stdout
