<DIV>I’ve been running the VMS Emulator on a Pi – in my case I ssh into the pi
and then start up a ‘screen’ session and run the vax emulator under the
screen. Then I can detach from the screen session (ctrl^A D) from
the screen session and then the ssh session. Connect back up later (from
anywhere: screen -r) and re-connect to the screen.</DIV>

<DIV>Seems to work great.</DIV>

<DIV class=moz-cite-prefix>I've seen this same problem when running the 780
simulator on other platforms. If you wait about a minutes after the boot has
finished the console usually starts responding again and is fine thereafter.
Does the console recover on the Raspberry Pi? I've not looked into what causes
this so far.<BR><BR>Matt<BR><BR>On 14/09/2012 20:42, Rob Jarratt

<P dir=ltr><SPAN lang=en-gb><FONT face=Calibri>I built SIMH on the Raspberry
Pi (Debian) and have been running it fairly successfully. Recently though it
has stopped responding to the console, for no reason I can determine. After it
has booted VMS (this is the VAX 780 emulation) I press enter to get the login
prompt and nothing happens. If I press CTRL-E it halts the emulation, but
fails to respond to any further key presses at the sim> prompt. If I change
the console to be telnet then I can use telnet to log in to the machine etc,
perfectly normally. This is really puzzling, has anyone ever seen something
like this?</FONT></SPAN><SPAN lang=en-gb></SPAN></P>
