No this is not how to do it. We don't want weirdass ioctls for each different tty device type. There are two ways this can work. The first is actually done by plenty of real physical hardware and that is to simply update the termios of the logical channel to reflect the settings negotiated by the link layer below (in your course USB ACM). If that isn't sufficient then implement an ioctl that could work for *ALL* tty devices - for example return a termios structure indicating the relevant values on top of the current tty termios settings not some USB ACM magic object.
