UART_GET_BAUD_RATE(9)						 16x50 UART Driver					     UART_GET_BAUD_RATE(9)

NAME

       uart_get_baud_rate - return baud rate for a particular port

SYNOPSIS

       unsigned int uart_get_baud_rate(struct uart_port * port, struct ktermios * termios, struct ktermios * old, unsigned int min,
				       unsigned int max);

ARGUMENTS

       port
	   uart_port structure describing the port in question.

       termios
	   desired termios settings.

       old
	   old termios (or NULL)

       min
	   minimum acceptable baud rate

       max
	   maximum acceptable baud rate

DESCRIPTION

       Decode the termios structure into a numeric baud rate, taking account of the magic 38400 baud rate (with spd_* flags), and mapping the B0
       rate to 9600 baud.

       If the new baud rate is invalid, try the old termios setting. If it's still invalid, we try 9600 baud.

       Update the termios structure to reflect the baud rate we're actually going to be using. Don't do this for the case where B0 is requested
       ("hang up").

NAME

       cfgetospeed - Gets the output baud rate for a terminal

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <termios.h>

       speed_t cfgetospeed(
	       const struct termios *termios_p);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       cfgetospeed():  XPG4, XPG4-UNIX

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Points to a termios structure containing the output baud rate.

DESCRIPTION

       The cfgetospeed() function extracts the output baud rate from the termios structure to which the termios_p parameter points.

       This function returns exactly the value in the termios data structure, without interpretation.

RETURN VALUES

       Upon successful completion, the cfgetospeed() function returns a value of type speed_t representing the output baud rate.
