+        interface. 
+
+        TelnetTerminal provides one additional callback which needs to be implemented in a derived
+        class: v_setupFailed(). This member will be called, when not all required telnet options are
+        supported by the telnet client. In this case, the communication will be switched back into
+        line-oriented mode and v_setupFailed() is called.
