Both - * must be the same. The POSIX standard interfaces, cfisetispeed() and - * cfisetospeed() are defined to be cfsetspeed() in termios.h. - * - * NOTE 3: A consequence of NOTE 1 is that you should never attempt to - * set the input and output baud to different values. - * - * Also, the following POSIX requirement cannot be supported: "If the input - * baud rate stored in the termios structure pointed to by termios_p is 0, - * the input baud rate given to the hardware will be the same as the output - * baud rate stored in the termios structure." - * - * NOTE 2. In Nuttx, the speed_t is defined to be uint32_t and the baud - * encodings of termios.h are the actual baud values themselves. Therefore, - * any baud value can be provided as the speed argument here. However, if - * you do so, your code will *NOT* be portable to other environments where - * speed_t is smaller and where the termios.h baud values are encoded! To - * avoid portability issues, use the baud definitions in termios.h! - * - * Linux, for example, would require this (also non-portable) sequence: - * - * cfsetispeed(termiosp, BOTHER); - * termiosp->c_ispeed = baud; - * - * cfsetospeed(termiosp, BOTHER); - * termiosp->c_ospeed = baud; - * - * Input Parameters: - * termiosp - The termiosp argument is a pointer to a termios structure. - * speed - The new input speed - * - * Returned Value: - * Baud is not checked...
