Vnc

VNC for EPOC ------------ This SIS file has been produced from a slightly modified version of the publicly available Java VNC client v3.3.3r2. It installs directly to the apps folder, and all functionality is accessible from the VNC interface. In practice the modifications are: - Added host and port fields to avoid the need for command line usage - Added a help option, to inform users how to move the small psion screens around over the larger VNC display Version 2 adds: - EPOC R6 is supported, unfortunately with a different SIS file. This adds functionality for the R6 menus and programmable keys ******************SEE INFORMATION BELOW******************** - Removed the port field - the host field now requires an entry of <host>:<port> - Any port under 10 is considered to be a VNC display number, (and thus has 5900 added to it to produce the real IP port) Any port over 10 is treated as a real IP port number - Added a saved hosts list. These reside in the file \System\Apps\Vnc\vnchosts.txt and should be <host>:<port> one per line. This file must be manually edited, it is not automatically updated - Scroll bars have been added, which means that the CTRL-SPACE sequence should not be needed. This option can be turned off in the options page, but this causes problems on R6 as you then can't move around the full screen. Latest version has ONLY been tested on a Psion Netbook,the Nokia 9210, and the Nokia 9210 EMULATOR. Previous version has been reported as working on the Revo, 5mx and Series 7. It also works sucessfully on the psion emulator, as supplied with the SDK. Remember though, it is a Java application and therefore requires the Java Virtual Machine to be loaded onto the psion. This comes pre-installed on some models, not others. The error message obtained when running VNC without the JVM is something like 'information not found' FILES IN KIT ------------ vnc-old.sis Version 1 of application - only works with R5 vncR5.sis Version 2 of application - for R5! vncR6.sis Version 2 of application - for R6! redirect.sis Application for use on R6 for troubleshooting cawt.jar Extra jar file - may be needed on some R6 machines TROUBLESHOOTING ---------------- 1. If you are using an R6 machine, ensure that you have the file cawt.jat installed, in \ext or \classes, or in the vnc app directory 2. The Nokia 9210 has very little memory available for applications after the Java Virtual Machine has loaded (~1.9Mb). VNC uses quite large buffers for screen and colour information, and thus WILL NOT WORK with servers where the display settings are hi-res and the colours are many. It DOES work with servers that have 640x480 resolution and 256 colours. Go higher, it may not work. 2. If you are using R6, try using the redirect application to direct java output to a file. This will give a reason for the failure 3. If you are using R5, java output will log to \logs\java\java.txt. This file will contain a reason for the failure 4. Send me an e-mail! FAQ --- I have had questions about the port field - basically, the port is the tcp/ip port that the vnc server is listening on. Vnc calls this a 'display number'. Vnc display number 0 is tcp/ip port 5900, vnc display number 1 is tcp/ip port 5901 etc. The port field needs the tcp/ip port, NOT the vnc display number. It is done this way because we frequently run VNC on non standard ports, and so use tcp/ip numbering in preference to vnc numbering. The default port used by the standard vnc server installation is 5900 - so use this number unless you have changed the server configuration in any way. On the 9210, the screen may be off the right hand of the Nokia display. To correct, select the menu option 'No Status Panel' INFO ----- Any comments or questions, please e-mail me: steve.allam@imhotek.com REGISTER -------- To register as a user, please send a mail to epocvnc@imhotek.com. The only details I would like is what psion you are using, and your e-mail address. I will *NOT* be using these details for anything other than letting you know of version changes, and a knowledge of what you are using allows me to verify that updates work on all platforms.
