    Unhappy Passwords

    I would like to know how to get a user to enter a password without echoing it to the screen.
    This code works but NOT if you press the backspace key when you make a mistake. Any Suggestions ?

    fprintf(stdout,"\nEnter password: ");
    while((ch = getch()) != '\r' && counter < CONNECT)
    user_input[counter++] = ch;

    if ( ch == '\b' && counter > 0 ) {
    } else {
        user_input[counter++] = ch;
    Some kind of test for backspace should have been self-evident.
