.TH "UART_GET_BAUD_RATE" "9" "17 July 2003" "" ""

.SH NAME
uart_get_baud_rate \- return baud rate for a particular port
.SH SYNOPSIS
.sp
\fB
.sp
unsigned int uart_get_baud_rate  (struct uart_port * \fIport\fB, struct termios * \fItermios\fB, struct termios * \fIold\fB, unsigned int \fImin\fB, unsigned int \fImax\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIport\fB\fR
uart_port structure describing the port in question.
.TP
\fB\fItermios\fB\fR
desired termios settings.
.TP
\fB\fIold\fB\fR
old termios (or NULL)
.TP
\fB\fImin\fB\fR
minimum acceptable baud rate
.TP
\fB\fImax\fB\fR
maximum acceptable baud rate
.SH "DESCRIPTION"
.PP
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.
.PP
If the new baud rate is invalid, try the old termios setting.
If it's still invalid, we try 9600 baud.
.PP
Update the \fItermios\fR structure to reflect the baud rate
we're actually going to be using.
