    Question ANSI Escape Sequences OR Scan of keyboard

    Hi there!
    I have two questions:

    1. I have tried the ANSI escape sequences towards
    a xterm and hyper terminal and can get the text
    reversed and in any given x,y position.

    What I cant get working is the reassignments of
    keys e.g
    ESC [0;68;"dir";13p or
    ESC [65;81p

    Does not take any effect...Does anyone know
    why or is there some clever steps need to be
    taken in order to get this working?

    2. How do I scan the keyboard in Unix for single
    hits e.g. the arrow keys.
    Using getch and similar commands needs a CR
    before it takes effect.


    Looking forward for your Answers!!

    Cheers // Samppa

    Try using kbhit() to monitor all keyboard strokes.

    kbhit()

    Isn't kbhit() used in PC environments?
    If it is usable in unix as what do I have
    to include?

    It has been a very long time since I had to do something like that, so I am not too sure about the correct names, but it is the right direction.

    kbhit() or something similar to it but with different name was a part of the "curses" library. The purpose of the "curses" library is to give you control of the console. I was using "curses" to create a visual interface inside the console.

    Hope this helps.

    P.S. When I get home, I see if I can find my old source using curses, and if I do, I will post the correct headers and functions to use. Cheers.
