History

dscho a84b3d072a pointerClient was still static. do not make requestedRegion empty without reason. the cursor handling for clients which don't handle CursorShape updates was completely broken. It originally was very complicated for performance reasons, however, in most cases it made performance even worse, because at idle times there was way too much checking going on, and furthermore, sometimes unnecessary updates were inevitable. The code now is much more elegant: the ClientRec structure knows exactly where it last painted the cursor, and the ScreenInfo structure knows where the cursor shall be. As a consequence there is no more rfbDrawCursor()/rfbUndrawCursor(), no more dontSendFramebufferUpdate, and no more isCursorDrawn. It is now possible to have clients which understand CursorShape updates and clients which don't at the same time. rfbSetCursor no longer has the option freeOld; this is obsolete, as the cursor structure knows what to free and what not.		20 years ago

README

In this stage (beta), there are two programs functional:

LinuxVNC <tty number>
	monitor a virtual console (text mode) of Linux. You need
	root privileges, or at least be in the "tty" group, because
	it reads /dev/vcsN and writes /dev/ttyN.
	It follows the same idea as WinVNC, x11vnc or OSXvnc, i.e. it
	takes an existing desktop and exports it via RFB (VNC), just that
	LinuxVNC exports text.

VNCommand <command> <args>
	executes <command> redirecting stdin from a vncviewer and stdout &
	stderr to the vnc clients. This might be renamed to vncTerm if
	there are some term capabilities added (up to now, bash doesn't look
	nice). Colours and other ANSI sequences need to be added.

My original plan was to create a program named vncTerm. It was meant to
overcome incompatibilities between different TERMs, but I found "screen" to
be just such a program. Maybe once some time in the future I'll make a
patch for screen to use VNConsole to export it's contents via RFB...

These two programs are a simple application of LibVNCServer with a small
console layer in between (VNConsole). You can use them under the terms
(not vncTerms ;-) of the GPL. They where written by Johannes E. Schindelin.
