        * A driver specific command, STC_PPCTIMEOUT, has been added to  *
        * the stc ioctl().  This command requires a parameter for time. *
        * This parameter specifies the amount of time after which to    *
        * time out. This timeout call is only in-effect during close(). *
        * It prevents close() from taking too long to complete.         *
        * This command ONLY applies to stc parallel ports.              *
        * SEE "Special Install Instructions", below, for more detail.   *
