Hi Mark!
Do you know anyone with experience of DTSS? On Bernd Ulmann's machine, FASOLT, DTSS$CLERK is stuck in LEF, apparently waiting for something that will never happen, and has come up like that through at least two consecutive reboots. I don't know whether he doesn't know how to fix it or hasn't noticed. I don't like to bother him because I know he is very busy, so I'd prefer to be able to offer some suggestions before raising the matter. My own experience, such as it is, is only that DTSS is a nice idea when it works but a real pain when it doesn't. If it isn't fixed before the last Sunday in October, it will cause a slight problem. Any ideas?
Regards,
Malcolm.

Both have their issues but then, so does xterm. I found so many issues with
the Xorg issue of xterm that I'm now building it from source; not that that

If you find any, I'm all ears. At the moment I'm not aware of any issues in xterm, but I have fixed bugs in it in the past.

Rob,
This is what I have:
At the DEC Legacy side I have a Draytek router with a USB data stick plugged in the back. As there is no ADSL connection it fails over to the datastick. I have NAT setup in the router to forward 4711 traffic to a laptop running Johnny's bridge. The bridge is configured to link with my home static IP address bridge running off hecnet.eu.
At the home side I have my Mikrotik configured to forward 4711 traffic to the HP microserver running Johnny's bridge. This is configured both with the standard link to psilo and with the dynamic IP address of the USB data stick.
When I first get the stick up and running I ssh into the HP microserver, edit bridge.conf with the IP address of the USB datastick and restart the bridge on both ends. If the IP address changes during the day I repeat this process. IIRC at the last DEC Legacy it happened a few times, primarily when the mobile signal dropped off rather than anything that looked more systematic from the carrier's point of view.
I'm trying to repeat this set up before this DEC Legacy at home. I've also done this in the past using the stick plugged into an ubuntu laptop and iptables, but I always find there are too many demons there (although I'm a lot more confident having gone through the pain with the Mikotik which uses the same mechanism).
I got distracted yesterday when I accidently overwrote the SRM console of a PICMG industrial Alpha I was looking to get OpenVMS installed on with AlphaBIOS (the Windows NT boot firmware). Apparently on these machines you can only have one or other of SRM or AlphaBios but not both. I was then left with a machine that failed on boot till I changed the CR2302 battery. Then it would boot but wouldn't load the firmware update from CDROM (to get it back to SRM) because it said the ROM was protected. I wrote a floppy with the firmware update which would then boot to the SRM update console, but that was hanging at erase.
I decided to call it a night after that!
Regards, Mark.

I was going to have a go at this today, but thinking about it I am not sure this can work at DEC Legacy or even here at home because it would always be behind NAT. Can we make this work with NAT? What ports would you need?
Nevertheless I have it configured with DECnet and I have entered the two SNMP commands below (I used the public community name, not sure if that is right because I know very little about SNMP).
The information you wanted was:
Your external IP Addres: 86.4.69.74
Your external FQDN: jarratt.dyndns.org
Is this a dynamic IP: yes
The DECnet area at this location: 5
The source interface on your router: Ethernet0
The email address you want updates sent to: rob at jarratt.me.uk (not sure if this is what you mean, this goes to my regular email address, are we talking about some email capability in the router?)
The snmp community from the above directions: public
I hope that is the information you need.

Dave, I was trained as a chemist but that is a long time ago (30 years).
I've been led astray by a Burroughs mainframe and have earned my money
in IT ever since with one exception: in 2012 I taught chemistry for 2
months. Oh boy, secondary school did change a lot in 40 years!

It's a capacitor that is rated to be placed across (hence 'X') the AC
line. They are usually applied in just that situation, and are
basically for filtration. However, their secondary purpose is as a
"sacrificial" component to protect the rest of the power supply in the
event of a large differential glitch between the two AC lines.
One must never place a "regular" (i.e., non-X-rated) capacitor in
place of one, though. Capacitors designed for such duty are usually
physically marked with an 'X'.

The 'X' capacitor? Actually I'd not want to run a big power supply

The Netherlands tends to follow German standards, so DIN and T V classifications are rather familiar to us. We do have KEMA standards though (Keuring Electrische Matarialen Arnhem). These guys are pretty thorough, they are often more demanding than what the Germans throw at electrical products.

a little more detail. the x means it uses Class X flame retardant dialectic -- in Germany for sure and probably most the eu, class X dialectic is required if you add filtering.
any filter cap that goes between the mains and neutral had be made of class X (or class Y if my memory serves me) material or you can't getter German equiv of the us UL for the device [google this if you want to understand more].
that said, the other thing you will see across mains for safety is a semi-conductor called an MOV (metal oxides varister). it has two pins and looks like a cap often orange red or blue and very glossy material but I would not bet on the color.
if the designers of the ps assumed an MOV i'd make sure you replace with that not a filter cap.

Typically you tftp them.
If the version you already have on the router supports it SCP and HTTP
might also be options.

Hello!
Oh wow. I agree.
But that Eclipse. I have fond memories of listening to either a Nova-2
or a Nova-3 or a -4, who evolved into an Eclipse working their way
through phototypesetting output and making it available to a variety
of output devices.
Including two first generation laser based ones and one proof device.
It seems like a full century today. But it was about one half to one
third of that.
That's why Dave that Eclipse is calling me.
But enough off-topic.

It's a capacitor that is rated to be placed across (hence 'X') the AC
line. They are usually applied in just that situation, and are
basically for filtration. However, their secondary purpose is as a
"sacrificial" component to protect the rest of the power supply in the
event of a large differential glitch between the two AC lines.
One must never place a "regular" (i.e., non-X-rated) capacitor in
place of one, though. Capacitors designed for such duty are usually
physically marked with an 'X'.

In fact, you don't. Open it up, replace the electrolytes. Near them you
may find a blown small element which is not needed really.
The 'X' capacitor? Actually I'd not want to run a big power supply without
that. They're usually not difficult to find, or to replace.

Yes, it's DECCOLM and there is a test for this. In fact, there are

I just realized I read a previous line of yours too quickly. I read

Oh well. My fault.
Doh! Just checked iterm2, and it also fails on DECCOLM...
Both have their issues but then, so does xterm. I found so many issues with
the Xorg issue of xterm that I'm now building it from source; not that that
doesn't have issues too, it's just not as many.

Selected some arabic language on your MAC, running the terminal,
typing in there, and in the terminal you have telnetted to some VMS
box.
Yes, essentially, Terminal.app will not accept Arabic letter input
but displays Arabic text (incorrectly, without ligatures).
I've tried this both locally, over SSH and Telnet.
Again, I don't think this is a VMS issue.
In this case, I think it is not. But I think you can pretty much expect
there to be situations where it will break for you because VMS do not
really work correctly with UTF-8. Your best chance, if you really want
to do UTF-8 would be to write your own program to output the file.
That's not true. VMS is only transmitting bytes of data to his
terminal.app.
VMS does not have any knowledge of the usage of that transmitted data
by the
autonomous application that is digesting it at the end of the
connection; in
this case, Terminal.app.
VMS can wrap output, and for that VMS keeps track of printing characters
output, so it can know when it hits column 80... And at that point, it
inserts extra CR+LF in the stream.
Checking at terminal settings in VMS:
LFFILL and CRFILL will also mess you up.
Thinking a bit more, these two might actually not be a problem. I think a plain CR or LF will not occur in the middle of a multibyte sequence.
Broadcast will mess you up.
This one is because broadcast text can just as well pop up in the middle of a multibyte character. However, since I think the broadcast will only happen between complete I/O requests, chances might be low, unless you do multibyte characters in multiple I/O requests.
TTSYNC can output XOFF and XON characters to you at any time.
Correction, it was HOSTSYNC I was thinking of here.
Lowercase alters output.
Tab can replace the tab character with a number of spaces.
And of course, the WRAP issue mentioned previously.

It's a capacitor that is rated to be placed across (hence 'X') the AC
