+/**
+ * @file vnc-server.h
+ * @brief VNC server original written for eCos.
+ *
+ * The VNC server runs on the target platform and waits for a client
+ * (vncviewer program running on a PC) to connect via an ethernet connection
+ * (port 5900). Once a client has connected, the target platform has a
+ * virtual screen, keyboard and mouse.
+ *
+ * This port of the VNC server has been designed with some limitations in
+ * order to keep memory and processor power requirements to a minimum.
+ *
+ * The VNC client must accept the settings that the VNC server suggests (bits-per-pixel,
+ * number-of-colours and so on as specified at build time with the eCos configuration
+ * tool) or the VNC server will just disconnect.
+ *
+ * The VNC server only supports CoRRE encoding and RAW encoding for sending
+ * display data to the client.
+ *
+ * The VNC server does not support password authentication, the client is able
+ * to connect without the user typing in a password.
+ *
+ * Only one VNC client may connect to the VNC server at a time.
+ *
+ * In reality these limitations are not a problem.
+ *
