In this implementation,
\fBqiflush\fR, \fBtimeout\fR, and \fBwtimeout\fR may be macros.

The \fBnoraw\fR and \fBnocbreak\fR calls follow historical practice in that

Mixing raw/noraw and cbreak/nocbreak calls leads to tty driver
control states that are hard to predict or understand; it is not recommended.
