       ioctl - control devices

       tcsetattr - set terminal parameters

       LIB$DISABLE_CTRL - Disable CLI interception of control characters

       The  Digital  UNIX tcsetattr function provides functionality similar to
       the OpenVMS LIB$DISABLE_CTRL library routine.  To disable control char‐
       acter  interception,  turn  off	the  ISIG  flag in the c_lflag termios
       structure.  To turn on the signal interception, set the	ISIG  flag  in
       the  termios structure and call tcsetattr again.	 It is typical to call
       the tcgetattr to determine the current terminal settings, modify	 these
       settings, and set the changed settings with the tcsetattr function.  It
       is also important to reset the original tty settings before exiting the
       program	both during normal exit and upon receipt of a termination sig‐
       nal.  The tcgetattr and tcsetattr functions are POSIX front ends to the
       ioctl system call.
