The AT&T Dataphone 212A sets required a dataphone with dial to work.
You dialed manually and pushed the data button and the modem would
take over and come up with carrier if the remote side answered.
It was kind of like dialing and pushing HOLD for the modem to take over.

I think there was a hack you could do to use it phone-less dialing from
a non-dataphone set.
