27\section line_model_monitor_page_sec_1 What does it do?
28 This code controls a GUI window, which provides monitoring of the internal status
29 of a telephone line modem. It shows, graphically:
30
31 - the spectrum of the received signal.
32 - the line model in use (when a known line model is being used).
33 - the adapted coefficients of the canceller.
34
35\section line_model_monitor_page_sec_2 How does it work?
36 This code uses the FLTK cross platform GUI toolkit. It works on X11 and Windows platforms.
37 In addition to the basic FLTK toolkit, fltk_cartesian is also required.
