Swapped the two 8251, same thing. So the 8251 might not be the problem here.
I’m going to check the MC1488 and if it’s not that, FW issue?
Just went full @adriansdigitalbasement.com on it. Looks like the D8251A is the culprit. Can’t find one on any of my spare boards.

AMD 8251A TXD (pin19)
→ MC1488 2A/2B (pins4&5 tied)
→ MC1488 2Y (pin6)
→ DB9 pin2 (TX out)
RS-232 Chips on the Board:
MC1489 / DS1489 = Receiver
RS-232 → TTL
MC1488 / DS1488 = Driver
TTL → RS-232
Pin 2 and 3 of the RS232 interface are going each in one of the chips there. Gotta go read the datasheet.

1. Insert small tool in hole.
2. Carefully lift the crt cover just over the main casing. Slide it backwards so the brightness adjuster pin does not break.
3. Undo CRT connector (and be amazed by my 3D modeling skills of recreating the locking mechanism.
I think it’s time I investigate why this guy doesn’t send anything on its TX pin.
