Mike,

>   1) Is there a protocol document for it?

No.  It should be written down, and I should probably be part of the
writing, and I know some questions that need to be answered, and
I know where some of the answers are, but I haven't had time to do it.

>   2) Public domain software?  Where is it on the net?

Yes.  On 'arpa.berkeley.edu' you may anonymously ftp 'pub/tn3270tar'
(in binary mode).

>   3) Types of machines its available for?

It works on 'all' 4.2/4.3 Unices (though there is a bug, simple to fix,
which makes it VERRRY slow on 4.2 machines).  I am working on a version
for MSDOS (really PCDOS), and may be done fairly soon.  In addition,
FTP Software has a beta test version for MSDOS.  In addition, IBM announced
a version (derived from a different version) for PC's.  In addition,
Ungermann-Bass has some interest in this area (as may other vendors).

I don't know of anyone who has ported it to VMS, though we may be
doing that at Berkeley soon (using a newly restructured tn3270
we are using locally).

>   4) Works with what flavors of IBM mainframes? (MVS VM??)

I think it works with all 2 of the the VM OS's (IBM/Wisconsin's and
the Spartacus/Fibronics).  In the MVS case things are a bit less clear.
In general it seems to function (at some level) with code derived
from the UCLA base.  I'm not sure about the other products (many of
them do '3270 - to - host over the network'.
