Linux 2.6 - man page for cfsetospeed (linux section 3posix)

CFSETOSPEED(P)			    POSIX Programmer's Manual			   CFSETOSPEED(P)

NAME
       cfsetospeed - set output baud rate

SYNOPSIS
       #include <termios.h>

       int cfsetospeed(struct termios *termios_p, speed_t speed);

DESCRIPTION
       The  cfsetospeed() function shall set the output baud rate stored in the structure pointed
       to by termios_p to speed.

       There shall be no effect on the baud rates set in the hardware until a subsequent success-
       ful  call to tcsetattr() with the same termios structure. Similarly, errors resulting from
       attempts to set baud rates not supported by the terminal device need not be detected until
       the tcsetattr() function is called.

RETURN VALUE
       Upon  successful  completion,  cfsetospeed() shall return 0; otherwise, it shall return -1
       and errno may be set to indicate the error.

ERRORS
       The cfsetospeed() function may fail if:

       EINVAL The speed value is not a valid baud rate.

       EINVAL The value of speed is outside the range of possible speed values	as  specified  in
	      <termios.h>.
