It should. TAP/TUN devices normally are network protocol agnostic.


I am using MinGW64/MSYS and LLVM environments and Eclipse/CDT IDE
editor. I already implemented WinSock2 API access into it.



I learned that WinSock2 API provides DECnet access.  Does anyone have

Depends on what you mean by "experience". I have a Windows XP box 
running DECnet here.

I plan to adding SDL2 API access for graphics console terminal (VAX
emulation) later.

Part of OpenVPN has tun/tap for Windows. And windows does software
bridges which you can bridge the tap to an Ethernet, or even among other
taps.. there is code in Qemu that'll talk to the tap driver.

As a footnote here is how it's done

possibly just copy the code just in.. or at least see how it's done.

Re: [Simh] ts10 and mse (my new emulator) (WAS: RE: Klh10 vs Simh)

2017-02-20 Thread Mark Pizzolato 
I’m not familiar with what device connectivity TS10 and MSE have implemented.

Is it simulating Ethernet devices?

Point to Point network devices?

Are these tun/tap connections merely used to connect simulators to each other
in the same system or are they also expected to be part of how connectivity I
achieved between simulators and the host system and/or the outside world?

I ask these questions since they’ve all been solved on Windows and Unix hosts
in the simh codebase.  The simh Ethernet functionality provides Ethernet frame
delivery to/from the local LAN and/or to/from the host system directly.  
Ethernet
frames can also be delivered to remote networks via UDP and thus direct
participations in HECnet is possible.  More than likely, the simh sim_ether code
wouldn’t fit directly into TS10 or MSE, but the details of how this problem has
already been solved would certainly be a useful in getting to where you’re 
going.

Step back from the focus on tun/tap and/or Winsock and think packet delivery
and reception.  Tun/tap is one solution to that problem on some platforms.
Simh’s Ethernet layer can talk via tun/tap on Unix hosts.  It can talk directly
to a LAN interface on Unix and Windows hosts.

10 Years ago, on Windows, we thought we needed some sort of package like
OpenVPN in combination with pcap to facilitate bridging.  As it turned out
(only on Windows), we didn’t need that at all once it was realized that we
could talk back and forth with the host system (using pcap) if we padded
pcap received packets to the minimum ethernet frame size.  We received
short packets since pcap captured them before they’d made it to the LAN
driver which would normally have padded them to the minimal frame size.

If you explore these ideas, feel free to ask questions here or directly to me.

DECnet for Windows? Yeah, if you have patchworks installed it is another socket 
transport. I ported a telnet client and SBBS 3.0 to DECnet. Not terribly useful 
today, but you can take windsock programs and alter them to run over DECnet 
with tweaking Not that there's an audience for that kind of thing

[Simh] ts10 and mse (my new emulator) (WAS: RE: Klh10 vs Simh)

2017-02-19 Thread Tim Stark 
Folks,

I searched ts10 through my old big mailbox and discovered one email that 
mentioned my old ts10 emulator.

My old ts10 emulator is now on Github website.
https://github.com/fsword7/ts10

I removed old CVS files from my ts10 project and initialized git repo files.  I 
successfully pushed it into GitHub today.  My old ts10 repo still exists on 
sourceforge.

I tried port it to Windows but some compatible problems.  I reverted files back 
to original files.  Windows still do not support TAP/TUN drivers.  TS10 
emulator supports only Linux/UNIX architecture hosts at this time.

I started to develop my new emulator in C++ language from scratch for all 
platforms (Linux, OS X, and Windows) and it is now on GitHub. It called 
Multi-System Emulator system (mse). It is under very early alpha stage. I are 
implementing initial KS10 and KL10A/B emulation in progress.  I now use TOAD-1 
architecture manual because it is easier to read than scanned documents.  I 
will use switch and try-catch for exceptions instead of old longjump and array 
of function pointers.

My new mse repo is now on https://github.com/fsword7/mse

Tim

Tim Stark attempted to implement the KL10 with his TS10 emulator.  I think he 
got quite far, but I haven't tried running his implementation.
