 * Name: cfgetospeed
 *
 * Descripton:
 *   The cfgetospeed() function shall extract the output baud rate from the
 *   termios structure to which the termiosp argument points.
 *
 *   This function shall return exactly the value in the termios data
 *   structure, without interpretation.
 *
 *   NOTE 1: NuttX does not not control input/output baud rates independently
 *   Hense, this function is *identical* to cfgetispeed.
 *   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 may be returned here... not just those enumerated in
 *   termios.h
 *
 * Input Parameters:
 *   termiosp - The termiosp argument is a pointer to a termios structure.
 *
 * Returned Value:
 *   Encoded baud value from the termios structure. 
 *
