You're right, D6 seems to contain some version of the HIM code. This
is a surprise to me, I had thought all this time that it didn't appear in MTS until

later.

The ultimate reference for questions like this is the driver file
which is guaranteed to be correct since it was used to write the tapes
and disk pack. It contains entries for the HIM code. I don't know
how well it works in that version, but there is at least some chance
that D6 will support TCP connections in Hercules when the HIM code is

finished.

The copyright question is complicated. It's also not the only
question that is relevant, either. There may be other legal
restrictions that apply to these programs. Do you have any reference
for the idea that IBM let these go into the public domain?

Not a chance. The only mainframe code IBM has "released to the public" was
APL but its not public domain, it’s a very restrictive licence.
Modified versions are not allowed so people jump through hoops to provide
code to patch it.

I should have said there is a common misconception that VM/370 and pre MVS/SP operating systems are Public Domain because their copyrights have expired.
This isn't true, these products never were copyright, they always were public domain.
If the copyright on the first Mickey Mouse film has just expired IBM software is going to remain copyright until long after I am pushing up daisies.
