Huh, ok. Never saw that

Not sure what your point is. The displayable data in a 3270 data stream, as
sent to a 3270 device, is not ASCII as far as I've ever seen. Of course a
controller might rework it as an emulation thing, but I don't think any
3270s spoke ASCII, did they?

Ehhhhh...the 3270DS itself still isn't doing ASCII, I don't think.

That depends on the 3271 model.

My TSMBIRD was ASCII art on a 3277; is your ILRBIRD fancier?
ASCII ? 3277?
It's easier to believe EBCDIC character cell.
Or do 3277 data streams support ASCII?
