We do in fact have full-blown graphics modes in the terminal and have had for decades. You can switch xterm to Tex4014 mode at your leisure, although this might not have been the graphics you had in mind. I believe you can _still_ pay money to HP for the pleasure of using decterm, which emulates the VT340 and other REGIS-protocol terminals. One of the craziest hacks on graphics terminals was NCSA Telnet. It supported multiple detached Tek terminals as well as a raster graphics protocol called "ICR". It had its own TCP stack built in, and could offer these features even on DOS. One of the weirdest rigs I ever saw was a guy at college who browsed the web, with graphics, using NCSA Telnet on a PC/AT running PC-DOS, at a time when that computer was at least 10 years old.

Regarding Tek("Tektronix")-Graphics, here's an animated gif showing Tek4014 graphics... http://phk.freebsd.dk/AducLoran/animation2.gif http://phk.freebsd.dk/AducLoran/animation2.gif ...part of a Loran-C receiver made by Poul-Henning Kamp which aparently outputs these plots over its serial port. http://phk.freebsd.dk/AducLoran/ http://phk.freebsd.dk/AducLoran/ To play with it, for example gnuplot can output on an xterm running in tektronix-mode. Open an Xterm, then... * mkfifo /tmp/tek * cat /tmp/tek * Ctrl-Middle-Mouse menu: - show tek window - switch to tek window - (in Tek window:) hide vt window Open a second terminal (Xterm or any other) * start gnuplot, on the gnuplot-prompt * set term tek40xx * set output "/tmp/tek" * plot tan(x) {or whatever you want to plot} Using two separate terminal emulators, and the fifo, makes it easier to coordinate the two different modes, because frankly gnuplot doesn't switch sensibly between the two display modes and will clobber one or the other either with Tek control codes on the VT, or write the prompt over the graphics.
