1) There is a DOS version of VNC available at: http://c0w.inode.at/mjy/dosvnc.html There is even an 1MB RAM version!!! It requires just DOS and packet drivers, That's the VNC 'client' (the part the user interacts with on a local computer.) I'm looking for a DOS "server" - the part that runs on the remote system. I figure that at least in theory, the TCP support required would be drastically reduced since it would only need to support the VNC connection itself (one connection?) A one connection TCP can be pretty simple, as the current microcontroller implementations are demonstrating.
