      • instance

        public static DataSource instance()
        Provide access to a defined DataSource object.

        Note that this can be used to get the DataSource object once it's been created, even if it's not connected to the hardware yet.

        Returns:
        null until a DataSource has been created.
      • sendBytes

        void sendBytes​(byte[] bytes)
        Send output bytes, e.g. characters controlling operation, to the tester with small delays between the characters. This is used to reduce overrrun problems.
        Parameters:
        bytes - content to send
      • openPortButtonActionPerformed

        void openPortButtonActionPerformed​(java.awt.event.ActionEvent e)
        Open button has been pushed, create the actual display connection
        Parameters:
        e - Event driving this action
      • dispose

        public void dispose()
        Description copied from class: JmriJFrame
        When window is finally destroyed, remove it from the list of windows.

        Subclasses that over-ride this method must invoke this implementation with super.dispose() right before returning.

        Specified by:
        dispose in interface WindowInterface
        Overrides:
        dispose in class JmriJFrame

      • nextLine

        protected void nextLine​(java.lang.String s)
        Handle a new line from the device.
        • Check for version number and display
