Sorry I wrote software to push (and pull) software and data updates automatically way back when the only comms was dial up modems running at 1200 baud. As soon as autodial modems came out we wrote our own software and implemented it for our customers to replace manual methods which had been used in the past.

That was probably around 1984. Clear prior art! It even included recovery from point of failure, error checking (as not all modems were then) and numerous other 'modern' features.
