* NOTE 1: NuttX does not control input/output baud independently. 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
