From: dove at mit-dspg at mit-mc Could you add that mode to the tty driver? #define LLITIN 0100000 /* Don't translate input chars */ I can send a copy of our ttynew code if you like. It does what raw does but only for input (i.e. no translation and wakeup per each input char). (Actually, our driver wakes the proc up every .1s or input char or half full input buffer whichever comes last). LLITIN|LLITOUT allows one to implement screen editors that use 0200 bit tty chars for timing instead of padding with nulls. That appears to be the only way to use ambassadors at 19200b, since they treat nulls just like ordinary chars and will bust if you try to pad with them. In any case, it cuts down on the # of chars sent.
