[Simh] Raspbian repository versus Github current

Hello!
Am I correct in that the version stored somewhere in the Raspbian
repositories is too old to properly grok the idea of using a physical
serial port to talk to a terminal device versus the current Github
one?

I'm planning a project, note the keyword, "planning" in that I'd be
running an appropriate release of UNIX or BSD on the PDP-11 emulated,
and it would need a serial port to talk to a terminal device.

Networking is as it happens optional.

The simh Current version at https://github.com/simh/simh can connect
simulated serial port to a physical serial port on the host system. Linux
packaged simh versions are some 8 years old and don't have that functionality.

$ git clone https://github.com/simh/simh
$ cd simh
$ make pdp11

A simh simulator accessing the host system's serial ports on Linux either
requires running as root or changing the permissions on the serial port
device(s) in /dev

Hello!
Then the question becomes having the console, that is the simh prompt,
be seen on what's connecting to the Raspberry Pi via SSH startup that
simh/PDP-11 one and after UNIX finishes starting up, the serial port
itself provides the user prompt. How would I set that up?
