Console terminal switch and/or reverse terminal server suggestion?

I thought about using a DECserver in reverse LAT for this, but AFAIK the only way to connect to a DECserver in reverse is from a real host system, like VMS or RSX. That means my console terminal would have to connect to a VAX, log in, and from there connect out again to the DECserver and the PDP-11 or 8 console port. Kinda complicated and ugly. With reverse LAT enabled, you can connect to the ports from an attached terminal. I currently forget how, but it wasn't very hard. It's how I tested having VMS 1.50 on my VT420. I don t think there s any way to have one terminal server connect directly to another terminal server w/o a host system in between, at least not with LAT. Telnet would be OK, if anybody can recommend a multi-port telnet terminal server that works in reverse. It d be especially cool if it can telnet to itself then I could just connect directly from one port on the server to another. Anyway, I was thinking that I can t be the only collector with a bunch of computers and room for only one console, so I thought I d ask what other people are using.

The DS200 will do it just fine though. ... got a DECserver-200/MC - no problem there. Ummm, does anybody have the load software kit for VMS? I just plugged my DS200/MC in only to discover that I don't have the boot image for it. Thanks, Bob

We are discussing the concepts of running DECNET via TOPS over the implied serial connectors that are now available? Correct? In this case, i'm using klh10. Once this is ironed out I will likely take a crack at it on SIMH's KS10 emulation. The big problem is the circumstances behind it. You'd need to rebuild your entire monitor to support it, I believe. --- These problems are also Dave's fault as supplied by four dozen Yetis, and an equal amount of Cybernen.

I'll go dust off an old DECserver and plug it in, and then I'll give it a try. With reservation for the DS100, which I think cannot do reverse LAT. It might also not be able to define services. It's been so long since I used one them, that I'm not totally sure. The DS200 will do it just fine though. Johnny

Yes, like that. They are a 3u unit with 30 ports. There's a rarer version called the Portmaster 2 (without the E) that has 10 ports and is only 1u high. Exactly the same circuit board just a smaller case. Not sure what you mean by connect from one port to another? You can come in with a terminal on one port (I use a vt320) and bring up a login port. You log in to the terminal server. At this point you can attach to any other port. You can also telnet in via Ethernet. I've never tried it but I'm sure you can connect via a serial port on one of your machines (just as if it was a terminal) and log in to get you the prompt to connect to another port.

Anyway, I was thinking that I can t be the only collector with a bunch of computers and room for only one console, so I thought I d ask what other people are using. No. Any DECserver can act both as ingress and egress, without any intermediate system. What you need to do is to set up a service. Any computer with LAT can set up one or several services. But any terminal server can also setup a service. And with a terminal on a DECserver, you connect to a service. Don't matter who is presenting the service. Reverse LAT is slightly different, in that you can connect to an outgoing port on a DECserver without using a service, by using reverse LAT. You just tell which DECserver, and which port on that DECserver to connect to. But you don't need reverse LAT in your case. Connect all console interfaces to ports on a DECserver. Define all ports access as remote, and setup services for all of them, and you're in business. However, as you note, they will not really buffer anything, so it's not perfect. You'd need something like screen in Unix, with connections to each machine, in order to get buffering and so on working they way you want. Johnny

That means my console terminal would have to connect to a VAX, log in, and from there connect out again to the DECserver and the PDP-11 or 8 console port. Kinda complicated and ugly. My AlphaServer DS10 and PDP-11/83 console ports are connected to DECserver 90M, and I can connect to these consoles from terminals connected to this DECserver.

> I found the DECserver 90TL does it but thry are rare. I didn t know a 90TL could do all that. It s a nice compact little box, but like you say they re hard to come by. Bob
