 * These are the most common definitions for tty ioctl numbers.
 * Most of them do not use the recommended _IOC(), but there is
 * probably some source code out there hardcoding the number,
 * so we might as well use them for all new platforms.
 *
 * The architectures that use different values here typically
 * try to be compatible with some Unix variants for the same
