(Actually, turning CBREAK on is like turning ICANON *off*, but....)

No, "raw" and "cbreak" are different.

"raw" means *RAW*, as in "no input processing of any sort, not even
checking for the interrupt or quit characters, or for ^S and ^Q, and
8-bit input/output with no parity, and no *output* processing either". 

"cbreak" means "don't do input editing, i.e. no erase or kill character,
*but* do *all* the output processing requested by the other mode bits,
and check for the interrupt and quit characters, as well as for ^S and
^Q."

Not the same at all.
