Thanks, Johnny. I found my notes on when I did this in V6. I had the
following in my ini file:
set dci en
set dci lines=8
set dco 7b
att dci 5555
and when I boot V6 and telnet into it I get this:
telnet localhost 5555
Trying ::1...
Connected to localhost.
Escape character is '^]'.
Connected to the PDP-11 simulator DCI device, line 0
login: dmr
Login incorrect.
Name: root
#
Which is great. I tried the same in V7 after editing /etc/ttys, which is
different in V7 than V6, having lines like:
14console
00tty00
00tty01
Which I changed to:
14console
10tty00
10tty01
After reboot, no go though. The telnet session is unresponsive.
Any ideas?
Thanks,
Will

I haven't played with V7, but I assume there must either be an
/etc/ttys, or something similar, which tells Unix on which terminal
lines to start a login process at boot. Otherwise they are going to be
very silent.
Also, remember to hit enter, as they will not spontaneously print out
a prompt just because you telnet in. They have already printed a
prompt when the login program started.

Hi,
It's been a while since I used SimH pdp11 to do anything beyond boot
Unix V6/V7 for a single user. I would like to be able to use the V7
system in multiuser mode with multiple users and I can't quite wrap
my mind around the problem, so I am asking y'all for help. I am sure
I'm butchering the discussion as I'm a bit unclear on what device is
doing what, but ultimately I want to be able to telnet locally to a
port that the running Unix Version 7 will respond to with a TTY that
I can log in to. According to the document Setting Up Unix - Seventh
Edition by Charles B. Haley and Dennis M. Ritchie, V7:
The DC11 driver is set to run 4 lines. This can be changed in dc.c.
The DH11 driver is set to handle 3 DH11's with a full complement of
48 lines. If you have less, or more, you may want to edit dh.c.
The DN11 driver will handle 4 DN's. Edit dn.c.
The DU11 driver can only handle a single DU. This cannot be easily
changed.
The KL/DL driver is set up to run a single DL11-A, -B, or -C (the
console) and no DL11-E's. To change this, edit kl.c to have NKL11
reflect the total number of DL11-ABC's and NDL11 to reflect the
number of DL11-E's. So far as the driver is concerned, the difference
between the devices is their address.
This sounds promising as these seem like terminals to me and each has
plenty of lines if only I could get simh to serve up the devices and
attach them to telnet ports, and if Unix will actually provide ttys
on those devices.
I read the docs and tried adding variations of:
set dli lines=4
attach dli 3633
set dlO0 nodataset
set dlO1 nodataset
to my pdp11 boot.ini file, as well as dc versions of the above and
and and...
I telneted to port 3633 locally after each reconfiguration, but
didn't get any unix output on the telnet session.
I appreciate any helpful comments or suggestions.
Thanks,
Will
