Absence of evidence is not...
Who said that? :)
As I remember it was suddenly gone from my regular bookmark, and google
couldn't find it either. That was many years ago though.
Is it available on an IBM web site?

Subject: Re: 3270 programming
I don't think TN3270/TN3270E protocols are related to this manual.
They're basically just a layer used to pass the binary 3270 data stream
back and forth.
But Lennie has a good point. I have a printed copy -05 from 1990 and
it's pretty beat up. I seem to remember it on an IBM doc site until
(guessing) 2005 or so, then it was suddenly gone. Maybe someone made a
mistake in removing it, because it's certainly required for anybody who
wants to code their own 3720 screens, or simply wants to know how things
work.

3270 is supported via tn3270 and tn3270E. That’s the protocol supported by
IBM OSA or Visara CCA3074 etc. You can probably find some old coax manuals
for native 3270.

So if the protocol is still supported, and still used, and still a valid
programming interface, why is there no *current* manual available from IBM
documenting it?

I think IBM still supports 3270 access, if not the 3270s themselves.
But if the data stream hasn't changed since the -7 manual was published,
there's no need for an update...

Does IBM continue to support the device? If not, there's little
business case to provide user's manuals.
Regardless, some documentation is necessary as long as IBM products
depend on 3270 data streams.
