#include <curses.h>

I have been having problems trying to trap a single Escape character
in a couple of implementations of UNIX ie. AIX on the IBM RS/6000 and
UNIX V2 on the ICL Clan 500 machine. Below follows a test program that
will print out a message for every key pressed. However, the Escape
character does not come through when pressed the first time for the
above systems. I am using a freedom 100 terminal on the ICL Clan 500
and an IBM3151 terminal on the RS/6000. I know that it is possible
to trap a single Escape character in both these implementations...
it works in vi!

void main()
{
  int key;

  initscr();
  nonl();
  noecho();
  cbreak();
  keypad(stdscr,1);
  key = getch();
  while(key != 'Q' && key != 'q')
  {
    addstr("Key pressed = ");
    addch(key);
    addch('\n');
    refresh();
    key = getch();
  }
  endwin();
}

Does anyone out there have any suggestions?
