But in such case the "Output level" value (the first one) will be ignored.
If we suppose that the calls of reset() which were already done are ignored:

     if (term_in.f!=stdin) term_in.f=stdin,get(term_in);
     if (eoln(term_in)) get(term_in);

then the "Output level" value (the first one) cannot be skipped with <return>.

I cannot find any setup that does not lead to inconsistencies...

Which rules does pascal follow?
