+.SH NAME
+cfsetispeed \- set input baud rate
+.SH SYNOPSIS
+.LP
+\fB#include <termios.h>
+.br
+.sp
+int cfsetispeed(struct termios *\fP\fItermios_p\fP\fB, speed_t\fP
+\fIspeed\fP\fB);
+.br
+\fP
+.SH DESCRIPTION
+.LP
+The \fIcfsetispeed\fP() function shall set the input baud rate stored
+in the structure pointed to by \fItermios_p\fP to
+\fIspeed.\fP
+.LP
+There shall be no effect on the baud rates set in the hardware until
+a subsequent successful call to \fItcsetattr\fP() with the same \fBtermios\fP
+structure. Similarly, errors resulting from
+attempts to set baud rates not supported by the terminal device need
+not be detected until the \fItcsetattr\fP() function is called.
+.SH RETURN VALUE
+.LP
+Upon successful completion, \fIcfsetispeed\fP() shall return 0; otherwise,
+-1 shall be returned, and \fIerrno\fP may be set to
+indicate the error.
+.SH ERRORS
+.LP
+The \fIcfsetispeed\fP() function may fail if:
+.TP 7
+.B EINVAL
+The \fIspeed\fP value is not a valid baud rate.
+.TP 7
+.B EINVAL
+The value of \fIspeed\fP is outside the range of possible speed values
+as specified in \fI<termios.h>\fP.
