return the output baud rate that is stored in a termios structure
#include <termios.h> speed_t cfgetospeed( const struct termios *termios_p );
The cfgetospeed() function returns the output baud rate that is stored in the termios structure pointed to by termios_p.
A valid termios control structure for an opened device can be obtained using the tcgetattr() function.
the output baud rate stored in *termios_p.
If an error occurs, (-1) is returned and errno is set.
