Try this from a program:

    Flush any waiting keyboard input
    characters.

    Write to screen:  <ESC>[6n           (Request cursor position report)

    Test to see if any characters 
    are waiting in the keyboard buffer

    If not, then ANSI.SYS (or an equivalent
    driver) is NOT present.

    Eat any waiting characters.

Good luck.
