DEC's TOPS-10 OS optionally echos for user programs and does it remotely via its "ANF-10" networking protocols. It allows a user program to declare its own set of input characters that stop echoing. It goes to a lot of trouble to make certain that the first characters that are not supposed to echo, don't (like passwords). I recall some technical device they call "pipeline echo markers". My own inclination is that any protocol adopted in this day and age should be able to locally generate cursor movements in response to cursor movement keys. John Wobus Syracuse University
