Just set the baud rate to 921600. You may need to write an app to do this
directly via the TERMIOS2 ioctl because it seems three years ago is a bit
quick for the glibc maintainers to keep up.
Basically set the baud to BOTHER, set the ispeed = ospeed = 921600 and
the kernel will do its best to give you your request
