Correct. It is the other port on the Zilog chip.

No, I haven't used it. It would be no more compatible to the 6551 based
Super Serial Card than the //gs serial port is. That means if you use the
firmware it is reasonably compatible but if you talk directly to the
hardware then it is completely different. It would not even be the same
as the //gs as the 65c02 on the workstation card controls it instead
of the motherboard CPU.

>Has anyone ever run ADT to this port?

If ADT does not need to talk to the serial chip directly and can use the
firmware interface then it should be possible.
