VMS Help CC, Run-time functions, [no]raw  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Curses Screen Management macros that set and unset the terminal to
  and from raw mode.  The raw function performs the same task as the
  crmode macro except that raw does not imply nonl.  These macros
  only work with [w]getch and [w]getstr.

  Syntax:

       #include <curses.h>

       raw()
       noraw()
