Rare (cbreak) mode is precisely -ICANON -ECHO VMIN=1 VTIME=0, so read-char will hang until a character is available and then return it. That's why no min/time arguments are needed. You can of course call read-line or any other read-* in rare or raw mode, but it will chew up a lot of CPU going into and out of kernel mode for every character.
(with-raw-mode port min time thunk), (without-interrupt-chars port thunk), and (without-echo port thunk)?- Harold
