+The Linux implementation of this interface may differ (consult
+the corresponding Linux manual page for details of Linux behavior),

+.SH NAME
+cfsetispeed
+\(em set input baud rate
+.SH SYNOPSIS
+.LP
+.nf
+#include <termios.h>
+.P
+int cfsetispeed(struct termios *\fItermios_p\fP, speed_t \fIspeed\fP);
+.fi
+.SH DESCRIPTION
+The
+\fIcfsetispeed\fR()
+function shall set the input baud rate stored in the structure pointed
+to by
+.IR termios_p
+to
+.IR speed.
+.P
+There shall be no effect on the baud rates set in the hardware until a
+subsequent successful call to
+\fItcsetattr\fR()
+with the same
+.BR termios
+structure. Similarly, errors resulting from attempts to set baud rates
+not supported by the terminal device need not be detected until the
+\fItcsetattr\fR()
+function is called.
+.SH "RETURN VALUE"
+Upon successful completion,
+\fIcfsetispeed\fR()
+shall return 0; otherwise, \-1 shall be returned, and
+.IR errno
+may be set to indicate the error.
+.SH ERRORS
+The
+\fIcfsetispeed\fR()
+function may fail if:
+.TP
+.BR EINVAL
+The
+.IR speed
+value is not a valid baud rate.
+.TP
+.BR EINVAL
+The value of
+.IR speed
+is outside the range of possible speed values as specified in
+.IR <termios.h> .
