Thanks Corni Cou or anyone else point me to the rfbcounter server example? The web site http://www.uk.research.att.com/archive/vnc/rfbcounter.html seems to have broken.

Not necessary, it only needs to know one (raw encoding should do) and convince the viewer it only supports that one. For what it's worth, the origional website (http://www.uk.research.att.com/archive/vnc) provided a tiny vnc-server-example to which you can connect a viewer In the viewer, you see a number (lcd-type display ;-) counting something. see http://www.uk.research.att.com/archive/vnc/rfbcounter.html for details It depends on the kind of lcd display but if it is a raster or dot-matrix one, then you can just map the lcd-pixels to vnc-server-pixels and provide that once someone is connected. (i wish my printer had such a display, just run `vncviewer printer` and see the display from miles away). > > Does anyone know whether it is possible to streamline the RFB > protocol for > execution on a 16-bit processor?

Then best use no compression, skips compression code and compression cpu usage.

If it is a touchabel lcd, you might do somethign with the mouse events. However, if it is for viewing only, just ignore the events by providing a view-only server. > > Regards > > Andrew > This message contains confidential information and is > intended only for the > individual named.
