FYI, and because you know I can't resist this :-) Supra have gone the odd route
on this one and separated it into %E and %G, each being 0 or 1. The default
is %E1 %G0, which is equivalent to %E1.

%En     Auto Retrain based on line quality monitoring
         %E0=Disabled (Default)
         %E1=Enable Auto Retrain based on line quality
%Gn     Rate Renegotiation (Fall Back/Forward) based on line quality monitor
        readings (Fall Forward only if "good" quality for period
set in S190)
         %G0=Disabled
         %G1=Enabled (Default)
