NAME

uart_get_baud_rate - return baud rate for a particular port

SYNOPSIS

"SYNOPSIS"

unsigned int uart_get_baud_rate (struct uart_port * port, struct termios * termios, struct termios * 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.
