*
* GUI_VNC_X_StartServer
*
* Function description
* To start the server, the following steps are executed
* - Make sure the TCP-IP stack is up and running
* - Init the server context and attach it to the layer
* - Start the thread (task) which runs the VNC server
* Notes:
* (1) The first part of the code initializes the TCP/IP stack. In a typical
* application, this is not required, since the stack should have already been
* initialized some other place.
* This could be done in a different module. (TCPIP_AssertInit() ?)
