2020 can only do three hundred something, my memory fails on the exact
number. Maybe it ended up being 376. 

It's not a problem as long as it's END NODE, decnet will negotiate the
smaller numer. The doc said that it only suports ONE serial
interface....

That makes sense, indeed for an end node the small MTU is no issue (other than the performance impact).   That may be how the 2020 people got away with that implementation.
