What is VNC ?
|
| 4 |
|
|
-------------
|
| 5 |
|
|
VNC is Virtual Network Computing, you have a 'viewer' running on one
|
| 6 |
|
|
machine which allows you to control the desktop of a different
|
| 7 |
|
|
machine via the VNC 'server'. The design allows the viewer and server
|
| 8 |
|
|
to run on different hardware and different operating systems yet
|
| 9 |
|
|
still work together. What this means in practice is that you can have
|
| 10 |
|
|
a Windoze desktop in a window on your X display or vice-versa.
|
| 11 |
|
|
The viewer has also been designed to be small and portable so it
|
| 12 |
|
|
seemed like a good candidate for a nano-X application.

Status of the nano-X port
|
| 20 |
|
|
-------------------------
|
| 21 |
|
|
The nano-X port is based on the VNC viewer for X, version 3.3.2.
|
| 22 |
|
|
This is the 2nd work-in-progress release, the main differences
|
| 23 |
|
|
from the previous release are:
|
| 24 |
|
|
|
| 25 |
|
|
+ Now uses GrSetSystemPalette() to handle 8-bit palette displays.
|
| 26 |
|
|
+ Builds for Microwindows 0.88pre8.
|
| 27 |
|
|
|
| 28 |
|
|
The features / limitations of this release are:
|
| 29 |
|
|
|
| 30 |
|
|
+ Compiled with Microwindows version 0.88pre8
|
| 31 |
|
|
+ Viewer tested on uClinux running on an Isicad Prisma 700
|
| 32 |
|
|
workstation with the serial mouse driver, the tty keyboard driver
|
| 33 |
|
|
and my own screen driver. The Prisma has a 1280 x 1024, 256 colour
|
| 34 |
|
|
display but it is not accessible as a frame buffer so needs a
|
| 35 |
|
|
custom microwindows screen driver.
|
| 36 |
|
|
+ Also tested with the X11 screen driver on Slackware Linux.
|
| 37 |
|
|
+ Tested with VNC servers running on NetBSD-Amiga and Slackware
|
| 38 |
|
|
Linux.
|
| 39 |
|
|
+ Only tested with an 8-bit palette display.
|
| 40 |
|
|
+ Keyboard handling is working but only for simple ASCII text, no
|
| 41 |
|
|
shift-clicking.
|
| 42 |
|
|
+ Mouse seems to work OK.
|
| 43 |
|
|
+ No way to scroll the screen if the viewer window is smaller than
|
| 44 |
|
|
the server's screen.
|
| 45 |
|
|
+ Runs very slowly on the Prisma, most likely due to the Prisma's
|
| 46 |
|
|
weird graphics interface.

Installation
|
| 49 |
|
|
------------
|
| 50 |
|
|
The tarball is intended to be unpacked in the src/demos subdirectory
|
| 51 |
|
|
of the Microwindows distribution. The makefiles have been adapted
|
| 52 |
|
|
from those used by the rest of the demo programs so it should build
|
| 53 |
|
|
from the top level 'make'. The resulting binary will appear as
|
| 54 |
|
|
src/bin/vnc. You will need a network connection to a VNC server
|
| 55 |
|
|
to do anything with it :-)
