No, raw and cooked mode is a Unix thing and predates DOS by a long
time. On Unix, tty devices (like serial ports) can be in raw or
canonical (AKA "cooked") mode. When in cooked mode, you can enable
things like conversion of cr->lf or vice versa, mapping
lowercase->uppercase, handling various control characters, xon/xoff
flow control, and so on.
