[Simh] EXT :Re: Simh Digest, Vol 172, Issue 4

Everything Dave said is right, with the additional consideration that maybe he just wants to run Motif directly on the simh VAX simulator using the QVSS board which can be enabled if the simulator is built with libsdl2-dev package available.

If this is the goal, then some folks have observed less than ideal (possibly useless) mouse tracking behavior on some host systems other than Windows.  I’m working right now with a developer (Ian Schofield) who has solved these along with performance issues in the sim_video code.  I expect that things will be clean enough to commit in the master branch ‘soon’.  When that happens, we’ll announce that fact to the list and the related open issues in the github issue system.

So, Phil, if this is what you want to do, you might want to wait a bit.  ☺

You have asked for a rather generic X how-to without providing much of the useful information needed to help instruct you.

The most important information is what X (windows/motif) Client you will be running the applications on – this is usually the guest OS (OpenVMS, Tru64, BSD, etc.) running in the SIMH simulation, and what X Server (usually run on the PC that you want to connect to the guest OS) that you will be running.

From your email we might presume OpenVMS on SIMH VAX, and the native X server (Gnome?) on Ubuntu. If you provide more server and client information, someone can provide more detailed instructions.

Generally:

1)      Install the X Client software (applications) on the virtual system (guest OS). If this is DecWindows/Motif on OpenVMS, read the fine installation manual - making sure to follow the AUTOGEN instructions to start up the windowing system on boot and adding enough reserved memory to prevent detached application crashes. :-)

2)      Install the X server on the graphical visualization system (usually a PC). This is already done if running Linux on a PC in graphical mode. On Windows, install your favorite X Server software (Pathworks, Hummingbird, Attachmate, PuTTY, MING, etc.)

3)      On the X Server side, make sure the permissions are set to allow the X Client’s  IP (guest OS IP) to display to the X Server.

4)      Connect from the X Server system to the X Client system via Telnet, SSH, or a native X Server connection interface, depending on the X Server system’s capabilities.

5)      On the X Client side, start up the X application (XClock, Xterm, etc.) and export the X application session to the X Server visualizer (PC). The export and start up method methods vary depending on the X Client and guest OS. I would recommend starting with XClock or XEyes as your simplest connection tests.

Subject: RE: [Simh] Problems running simH in Android

I did a little digging and struggled with typing a whole bunch on my
phone.

The problem you’re seeing is due to the Linux OS environment you’re
running under doesn’t support ‘raw’ mode for terminal I/O.  When you
start a simulator the traffic to/from the simulated console device is
expected to be exactly the characters that the user types on the console
keyboard.  To achieve this, the current tt mode is gathered with tcgetattr()
then those attributes are adjusted so that every character typed is received
without any interpretation by the OS and output is also not translated (i.e.
\n only sends a LF character instead of CRLF characters).  The error message,
you seeing is due to the call a tcsetattr() failing.

If you’re not comfortable digging into this yourself, then please create an
Issue at https://github.com/simh/simh/issues <https://github.com/simh/simh/issues%20> and spell out exactly how to
recreate your setup and reproduce the problem.

Greetings

I have been trying forever to get simh to run under the Termux Android shell app and got very close but no cigar. It builds okay but then when I try running it, it starts fine but when I go to run an OS,  I get this:

PDP-11 simulator V4.0-0 Current        git commit id: f2f4bfa8
sim> do rt1154f.ini
Disabling XQ
rt1154f.ini-3> b rk0
sim_ttrun() returned: Console input I/O error
sim>

Any ideas?

Thanks

Ray
