One method to do what you want would be to do the following:
1. Connect a TTL to RS-232 Converter to the serial port on the Raspberry Pi
https://www.amazon.com/Ultra-Compact-RS232-Converter-Female/dp/B00OPTOKI0
2. Enable the serial console on the Raspberry Pi.
Log-in to your Pi using the default username |pi| and password
|raspberry|*. *Then**issue the following command:
*sudo nano /boot/config.txt*
This will launch the nano text editor with sufficient privileges to
modify the file. Then use the arrow keys to navigate to the end of the
file and add the following line:
*enable_uart=1*
And that’s it! The next time you reboot your Raspberry Pi you’ll be
ready to move on to the task of actually attaching that funky USB serial
cable.
3. Connect a serial to ethernet adapter on each remote system.
https://www.amazon.com/CERRXIAN-Ethernet-Serial-Device-Converter/dp/B087J9F6LF/ref=sr_1_4?crid=1Z8M6ZR7Z1QRV&keywords=rs-232+to+ethernet&qid=1659446389&s=electronics&sprefix=rs-232+to+ethernet%2Celectronics%2C92&sr=1-4
Keep track of the ip addresses of the adapters.
4. Login to the Raspberry Pi on the terminal
5. Install telnet on the RPI
*sudo apt install telnet
*6. telnet <ip address of the remote system>
This will work with any Raspberry Pi, even the Pi Zero 2 W.
Note: Telnet will not do any terminal emulation or translation.
Configure your local terminal for the emulation you need or configure
the remote hosts to the terminal you are using.

Subject: [cctalk] Re: Connecting a physical terminal via LAN to Serial Port
I feel like a Raspberry Pi or similar would fit the bill for this
nicely.
Yes, but it wouldn't be ready to go ;). I would need to find a raspberry pi
with a
built in serial port and a flavor Linux already loaded on it plus configuration.
There are plenty of SERVER devices out there (i.e. take data from the serial
console of a device and present it over the LAN via TCP/IP and accessible by
Telnet, SSH, even HTTP) so I am hoping someone has a client device as well.

Ali,
Many of the "server" devices work both ways. So you can configure the ports to be
"host/server" or "terminal" ports. I think for example this
https://www.ebay.com/itm/402706717955
will let you have both types of ports. It’s a bit modern and complex but seems
to fit the bill..
