Sure it will, just start it like:

getty -in -l /usr/bin/pdp11 ttyS0 9600 vt100

(getty syntax will vary depending on the getty that's installed on your
machine. The syntax above works with "agetty" as distributed with
Debian GNU/Linux).

Or you can just run a normal getty on your serial port, and log into the
*nix via the serial port and run simh.

So, if you felt creative, you could do:

getty -in -l /usr/local/bin/pdp11-script.sh ttyS0 9600 vt100
sleep 10 # or whatever you feel like
getty -in -l /usr/local/bin/telnet-script.sh ttyS1 9600 vt100
sleep 1
getty -in -l /usr/local/bin/telnet-script.sh ttyS2 9600 vt100
sleep 1
getty -in -l /usr/local/bin/telnet-script.sh ttyS3 9600 vt100
sleep 1
getty -in -l /usr/local/bin/telnet-script.sh ttyS4 9600 vt100
sleep 1
# repeat as necessary

And have a pdp11-script.sh which sets up and runs simh appropriately,
and a telnet-script.sh like:

telnet localhost 10000

...assuming that you have port 10000 as the TCP port you gave to simh
for connections to your simulated DZ11.

I'm tempted to cook up a small Linux/simh image that'll do this.
