take a look at vtapeutils I found this, might have some insight as well. I highly recommend rather than taking any version from download, especially from a Linux distro, get and build your own version (Linux is pretty simple with latest versions) from source for your machine. I'm not a super expert but a problem I'd had with DASD forever has gone away with the latest.? I couldn't get anyone to look at it in my local circle, as they'd been away too long to want to jump start brain cells, but 6 months ago, I decided to give it my "every so often" try and built a version 4.5 which had no problem as I was having, and am now running what I wanted. Anyway, I think vtapeutil might do what you like for your TAP, AWS issues.? searching for anything on AWS tapes is horrible, since Amazon now pollutes that search. I'm certainly interested in anything you find with the actual hardware to hercules experiments. thanks Jim

Re: The first welcome message
Thanks!? Long time no see through the portals of time! I've been having this strange need to do some networking and after years of looking at a dlsw article, i've been trying to recreate it. This has gotten me interested again, and I almost think I had some partial success.? Other than it not working. I'd written about my adventure here: But what had brought me to VM/370 is that I've seen SIMH has a 360 emulator, and I've been curious to see what it'd take to get it running. In the status the following is in there:
- BOS/360:? ?Works.
- TSS/370:? ?Works.
- VM/370:? ? Works.
So obviously this interested me greatly as well! I've been trying to dig around in the dark and the best I can figure is that almost everything online is in AWS format, but SIMH needs its TAP format. There is a BOS image on bitsavers: I'll have to try that first, see if I can reproduce anything. In the meantime I do have a cisco 7200 (they are so cheap now!), and I've ordered a 4 port serial card, a serial cable with db25 end, and an IBM SDLC card, to see if I can get a PC to talk directly to Hercules with this setup.

The first welcome message
Hello!
I realized when I saw a familiar email address pop up in my mail here
that confirmed that we have a new member. Welcome to that lucky
individual. You will find that we are all friendly people in this
list. Nearly all questions regarding the groupings of VM are allowed
here, VM is indeed Virtual Machine, and it's a product of IBM that
goes back a very long time. To that extent those of us who do, run a
variety of VM that is VM/370 Release 6, and a very capable fellow
released to us several items. They are found in many places. Then
others took many turns to create releases that closely approximate
what is now Z/VM, that Z stands for I believe Zero Wait States. Or
perhaps it does not, it does go well with their families of System Z
machines.
Please feel free to ask your many questions.

Hi Mark, I wrote the HRC404DS mod. Nucleus extensions first appeared?in VM/SP. IBM needed a way to relocate code containing CMS APIs that used the DC AL4(Error address), or sometimes just DC AL4(*+4). VM/SP started?allowing DC AL4(1) to specify?an error return address. Allowing that construct allowed any code containing the *+4 value to work, and to be relocatable. Bob Bolch

I'm trying to find out if there is documentation on the SVC 203 halfword table. DMSITS has been extended by the person bright enough to add this bit.
FSVIEW: DMSITS AUXHRC F1?????????????????? Lines 1-1/1 F80[1-79]? FSVIEW V1.2.5

What I'm not finding is any external documentation on the table (DMSFNC) that SVC 203 (DMSITS) uses to determine what happens when I pick a particular halfword value.
At this point, I'm reading through the assembler code for both of these routines to understand what is going on.
So, if you bothered to read this far, if you know anything about SVC 203 and it's use of a halfword table to determine the function required ... I'm all ears.

Ah. Okay. That much is true, so apology accepted. :)
Would it be fair to say that Aethra is intended to be more focused on legacy guest operating systems whereas SDL is currently more focused on more modern guest operating systems? Yes? Would that be fair to say? I just want people to be clear regarding the difference between the two! Thanks.

More bleeding-edge is true enough, as SDL Hyperion Hercules tries hard to make the changes necessary to support IBM's latest and greatest versions of their "z" operating systems, but I take issue with your comment regarding stability, correctness and portability.
As far as I know SDL Hyperion Hercules is both absolutely correct AND quite stable and portable as well.
Why would you say such a thing, Jay?

Re: Doubts about setting up RSCS

Jay, not sure if you are addressing your question about the Hercules changes to me or Mike.
I never got as far as implementing anything with regard to the NJE node. ?I know there have been a few implementations by some individuals. ?They may better know the exact status of the Hercules changes. I would think they are licensed under the Q Public license which would allow distribution. ?BSC over TCP/IP might be the changes from a Hercules perspective.

I have had extensive discussions with the author of the enhancements.
It is a significant enhancement for RSCS and its attachment
capabilities.? It provides NJE node support in VM/370.? There are
Hercules enhancements that support the TCP/IP connection used by NJE.
The enhancements allow VM/370 to talk to VM/370 and S/370 MVS or modern
operating systems using NJE.? Transferring of files, in particular is
supported.
As far as I know, the Hercules changes are available.? Whether they are
part of the distribution, I do not know.
The vintage documentation will not describe how to configure RSCS for
this usage.? The author I am confident can point someone to the
documentation that would help in use of the enhancements.? This assumes
the author is willing to share the VM related software with the user.
My interest was in developing a Python based NJE-node as an add on to
SATK.? That would dramatically ease the movement of files between
VM/370, MVS 3.8 and modern systems.? All of the NJE-node supporting
products for Windows or Linux and the like are proprietary.? I was
looking at an Open Source implementation.? Very big job, and with the
author's reluctance to share his work, that sort of killed my momentum
for pursuing the idea.

Re: Doubts about setting up RSCS
#VMCE
Can you point me at the Hercules changes? I'll include them in Aethra, if allowed.
I have had extensive discussions with the author of the enhancements.
It is a significant enhancement for RSCS and its attachment
capabilities.? It provides NJE node support in VM/370.? There are
Hercules enhancements that support the TCP/IP connection used by NJE.
The enhancements allow VM/370 to talk to VM/370 and S/370 MVS or modern
operating systems using NJE.? Transferring of files, in particular is
supported.
As far as I know, the Hercules changes are available.? Whether they are
part of the distribution, I do not know.
The vintage documentation will not describe how to configure RSCS for
this usage.? The author I am confident can point someone to the
documentation that would help in use of the enhancements.? This assumes
the author is willing to share the VM related software with the user.
My interest was in developing a Python based NJE-node as an add on to
SATK.? That would dramatically ease the movement of files between
VM/370, MVS 3.8 and modern systems.? All of the NJE-node supporting
products for Windows or Linux and the like are proprietary.? I was
looking at an Open Source implementation.? Very big job, and with the
author's reluctance to share his work, that sort of killed my momentum
for pursuing the idea.
