That's not what I, at least, understand autobaud to mean - that's just
parity autosensing. (Autobaud, AIUI, is autosensing the speed.)

...on which the VT220 also works?

My guess would be that it's got nothing to do with what's on the data
pins, but rather is because one end thinks some kind of hardware flow
control is active and isn't seeing the signals saying "go ahead and
send".

I used to use tvi950s heavily, and while it was a long time ago, I
don't recall anything of the sort. Did you set the TVI to ignore the
incoming parity bits?
