[Simh] Telnet with PDP-11 Emulator

Wed Sep 20 13:27:29 EDT 2006

 I had a similar problem using Telnet with RSTS/E and NetBsd or Openbsd. 
The Netbsd and Openbsd worked once they were enabled for a TCP/IP address on Windows XP with Openvpn as a gateway to the host system, but no luck with console access, which I apparently needed to upgrade the OS as it seems to use vt100 emulation for the install tool.  On RSTS/E it was the pre-built image from the Delaware Delta project so I was not sure what parameters to use.

I’m running XP Pro SP2 also. I just started using SIMH a couple of weeks ago, so I don’t know much.

What OS are you running? I could never get the telnet to DZ feature to work with the pre-build ‘full’ RSTS/E environment I downloaded from the web. It started working after I re-installed RSTS/E from scratch. I just defaulted most of the install questions, so I don’t know what specific step did it. Maybe just having the DZ device enabled and configured during the install adds support for it. I used PDP-11 – RSTS/E from 1976-1980 and don’t remember the gory details about configuring the hardware and OS.

Or, if you are using another OS, then maybe it doesn’t know about the DZ device and isn’t listening to it.

Hi

Thanks for that 

Unfortunately when I configure as you suggest, the simulator starts correctly however when in a Windows command window typing ‘Telnet localhost’ gives the prompt ‘Connected to the PDP-11 Simulator’ and a flashing cursor. No further keystrokes are recognised, this is under Windows XP professional service pack 2

Any more ideas would be most welcome

Thanks for your time and help

Paul

Hello,

These commands work for me with PDP-11 simulator V3.6-1:

set DZ enabled
set DZ lines=8 
set DZ 7b 
attach -am DZ 23

You have to type HELLO to get an account number prompt.

Hi
It has been reported by a colleague of mine that when using SIMH version 2.9 and running under Windows XP Professional, that Telnet sessions worked correctly. However moving to the more recent versions, starting a Telnet session shows the connection to a PDP-11 but then stops i.e. does not continue to a log in prompt.
Are there any changes that may have affected this or issues we should be aware of or are we doing something stupid
;  Configure 8 off serial ports
SET DZ LINES=8
att dz 15000
from Windows command window
Telnet localhost 15000
The connection is made but there is no command prompt, any ideas
Regards

Paul King
