Some time ago I solicited help investigating how DEC VT terminals handle line wrapping, mainly for the purpose of accurate emulation. Having received assistance from very kind people -- many thanks! -- some of the findings have now been summarised at https://github.com/mattiase/wraptest, in

Would someone with a real DEC VT terminal be so kind and help settle, once and for all, the question about how they behave with respect to line-wrapping, exactly? It is something that isn't covered by any standard, nor by any of DEC's manuals, and there is a scarcity of information online that
