About Mocha VNC

Mocha VNC is an application for the Palm Computing (R) Platform. It enables you to have full, secure access to your work computer through an Internet or network connection. Using your Palm device, you can connect to your Linux/Mac or Windows computer and see the files, programs, and resources exactly as you would if you were sitting at your desk, just on a smaller screen.




Menu system and Quick buttons

The 4 Quick Buttons on a palm are used to make it easier to navigate the screen in Mocha VNC.

Zoom: Toggle if the full VNC Server screen is displayed or only part of it

Scroll: if in zoom mode, this function toggle if a pen movement on the screen will scroll the screen , or it will be a mouse movement

Keys: Gives a pop up menu, with a list of the most common PC keys

Right click: If pressed next tap on the screen will be a right click mouse action.

From menu - quick buttons, it is possible to change this default layout.

In the following we will describe the menu elements in details.

Menu - Connect to VNC Server

Use this command (or press Start in the first screen) to start a new session with your VNC Server

Menu - Disconnect

Menu - Quick Buttons

Menu - Preferences

Old Tungsten devices have limited dynamic memory. Mocha VNC will check the memory size on program start, and if it is low, display a warning, telling the program must use another type of memory, which will give a slower performance.

A hint:menu -about dialog display the current free heap size, which is the same as the dynamic memory.

If no pen input on the palm for some time, will force the Palm to power off, and a session will be lost. As default Mocha VNC will disable the power off function when a session exist.

Menu - Host List

Use this dialog to configure a set of VNC Server IP names. Notice it is possible to add a port number to the IP address. Example:

When tapping 'Host list' in the connect dialog, a pop up menu will be displayed and a host name can be selected.

    Set Up Your Server or Workstation for VNC access

    A VNC software package must be installed on the server, to allow Mocha VNC access to the server.

    See for details.

    Other servers exists, such as TightVNC, but not all supports the ZRLE encoding technology, which is preferred for low band width situations.

    If the UNIX/Linux version of realvnc is used, it is possible to select the size of the server screen with parameter -geometry.

       -geometry 800x600

    gives a useful screen and requires limited band width.
