about programable UART Baudrate

hello rugbybloke,

could you look at the following code that change the baudrate?

in the sopc builder i have set the option that divisor can be change.

and the result is when execute:

if (fd->dev->ioctl)

{

rc = fd->dev->ioctl(fd, req, arg);

}

it stop!

/********************************************************/

int main (void)

{

char* msg = "hello world";

FILE* fp;

struct termios* term;

fp = fopen ("/dev/uart1", "w");

if (fp)

{

term->c_ispeed=B57600;

ioctl(fp, TIOCMSET, term);

fprintf(fp, "%s",msg);

fclose (fp);

}

return 0;

}

/********************************************************/

could you show me how to do?

thank you!
