Glad to hear. Apparantly there is some subtle variants with regards to the
analogue components, so a state file that works for A may be slightly too
loud or too quiet for B. We need to expose the main volume in a simple way
FYI, the new cleanlyness (as far as the hardware allows *cough*) is due to an
improved statefile (thanks FDOM folks) and some tweaking via the
(undocumented *sigh*) modem echo and noise suppression commands.
Using -12db for echo and noise supression sounded too harsh for most people,
so I went back to -6db.
