Bad,
Sure others will chip in with more.
Our not very new 75's send all movements OOOI and return to stand themselves, the off message containing all door closure and engine start times.
Once aloft, automatic position reports are sent at predefined intervals, including FL and FOB.
As far as I am aware, (non-pilot) all the other stuf like departure/arrival fuel, snags and ops normal received each sector require Crew input to send.
Hope this helps a little bit.
