I noticed that whenever I boot up SimH VAX inside Putty under Windows, I get this peculiar message:

Connected to the VAX simulator

Why does the 6c always occur such that I need to do a carriage return first that result in a 22 ILL CMD, followed by a b dua0 to boot normally?

Under Windows, I have had enough problems with PuTTY as the boot console that I quit using it and just leave the Windows command window as the console. It is clumsy, but does the job. I use PuTTY to connect to serial and telnet sessions and it works very well.

Have you tried using the delete key in putting (configured to send a delete, not backspace of course) to delete those characters?


I run SimH in a Linux VM.


I do not know if the console is trying to auto-detect what type of terminal is attached and is failing to detect putty.

I've just tried using Tera Term Pro emulating VT320 and the 6c disappeared. However, the first key I pressed at the >>> prompt did not appear until the second time and the rest is normal.
Wonder if it's the terminal emulation mode that's giving the problem.

Btw, is it possible to autoboot from, let's say, DUA0 without having to keep typing >>> b dua0 each time I open a telnet console? The SimH 'dep -b bdr 0' didn't seem to work. I've tried >>> set boot dua0 and that didn't work either. Just wondering.

At the VAX console prompt (>>>smiley you will need to issue a SET BOOT DUA0:

Eisner was upgraded to the current Multinet Release. As part of that a new host key was generated. The old key was incompatible with newer Linux.

ssh to eisner is now giving (on linux) "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!" , Has the server key in fact changed ?

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.
