I've gotten OpenVMS V7.3 running (on SIMH emulator under MS Windows XP, but that shouldn't be relevant to my question). Things generally work well, but when I telnet to the machine, I can log in, and work for maybe 2 or 3 minutes, and the connection is terminated.
[New info: the same thing happens with FTP; the timeout is always 75 seconds.]
I assume this is some setting somewhere, but I can't figure out what it is. It isn't an idle-time timeout; I can be busy typing away. I haven't timed it precisely, but it seems to be in the 2 to 3 minute range. (The time interval is always the same, I just have no precise way of measuring it, which is why I give a 2-3 minute range).
My hope is that this is something trivial I'm overlooking. The console window (which isn't TELNET based) is fine, but has other limitations. IF anyone can point me to the right parameter or setting I'd appreciate it - I've been reading FAQs with no luck, which is sort of surprising, as I think this must have occurred for others.

Are you using HP TCPIP, MULTINET or TCPWARE on the OpenVMS side?
The problem might be your TELNET client? Which TELNET client are you using? I see that the FreeVMS Alpha emulator folks are including a copy of PuTTY for TELNET access. You might want to try that as your TELNET client for SIMH.
I'm currently using HP TCPIP on the OpenVMS side and TeraTerm on the client side for TELNET and SSH access to my emulated VAX machine under SIMH. I'm also running SIMH under Windows 7 64-bit (not that that would make any difference that I'm aware of). I'm not seeing any timeout problem.
"A few minutes" sure does sound like some sort of session keepalive interval.

I added some new info to the original message: I get the same behavior with FTP, and the timeout value is always 75 seconds. I found a few TCPIP parameters with that value, and tried changing the values to be bigger, with no luck.
(I played around with different telnet clients; I like Tera Term, and use it now as the console for SIMH, which is the only way I can stay connected for any length of time. The timeout is a huge and frustrating problem, as I have files that would take about 82 seconds to FTP, and I can't get them to the virtual VAX.)

malmberg December 12 2017 HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.

malmberg September 10 2017 https://sourceforge.net/p /vms-ports/wiki/VMSInstal lation/ For the most part just use VMS 6.1 media instead of 7.3. But why run the older release?
DoeveR August 07 2017 Where can I find the write up on running VMS 6.1 using the simh emulator?
