The standard UNIX tty driver will not output control-Ds except in raw mode; this is to prevent certain terminals from hanging up, giving up the carrier, becoming an ex-terminal, etc. But we have a beast that *likes* receiving control-Ds; it thinks they're color-change signals or some such. And we can't run it in raw mode; we need the XON/XOFF hand-shaking to slow down UNIX when it's talking too fast. My question is this: we'd like to take out that feature. What, if any, popular terminals will take their bits and go home if you dare say \004 to them? I seem to recall that DECwriter III's can be strapped that way, but I don't remember what happens if you disable that option.
