Cconrs is the one special case, because for TOS 1.00 and 1.02 it does
input *and* output. From TOS 1.04 onwards, nothing is output by Cconrs
on stdout when stdin is redirected. So, for TOS 1.04 and above all
functions are either exclusively input or output and could thus be
correctly handled by GEMDOS emulation.

I understand that this might be a lot of work with little benefit,
though, because this functions aren't used much. But at least this
missing feature should be documented then.
