/* Minimal termios.h for Hercules under VMS. The terminal functions
   are only barely used as originally intended. tcgetattr is used to
   fetch the terminal wrap setting for later restoration and tcsetattr
   is used to turn it off in order that the control panel does not end
   up scrolling up the screen after every instruction count update.
