.SH DESCRIPTION
.sp
.LP
The \fBcbreak()\fR function enables the character input mode. This overrides
any previous call to the \fBraw()\fR function and turns the \fBstty\fR flag
\fBICANON\fR off.
.sp
.LP
The \fBnocbreak()\fR function sets the line canonical mode and turns the
\fBstty\fR flag \fBICANON\fR on without touching the \fBISIG\fR or \fBIXON\fR
flags.
.sp
.LP
The \fBnoraw()\fR function sets the line canonical mode and turns the
\fBstty\fR flags \fBICANON\fR, \fBISIG\fR, and \fBIXON\fR all on.
.sp
.LP
The \fBraw()\fR function sets the character input mode and turns the \fBstty\fR
flags \fBICANON\fR, \fBISIG\fR, and \fBIXON\fR all off.  This mode provides
maximum control over input.
.sp
.LP
It is important to remember that the terminal may or may not be in  character
mode operation initially.   Most interactive programs require \fBcbreak()\fR to
be enabled.
.SH RETURN VALUES
.sp
.LP
On success, these functions return \fBOK\fR. Otherwise, they return \fBERR\fR.
.SH ERRORS
.sp
.LP
None.
