I'm not sure we should use ttyS for it. ttyS means 8250, a lot of existing code knows what ttyS is and what sort of ioctls and the like are assumed. A generic namespace needs not to be attached to a legacy naming (eg also put all serial ports in /dev/serial/0 /dev/serial/1 etc either via the tty layer or via systemd/udev) Alan -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
