Thanks. Seems to me the requirement is to update 'utelnet' with RFC2217 support, or create a replacement, so perhaps not considered in MicroPython's domain, but fingers crossed.I've asked in the Discussions
I did move things forward using : https://raw.githubusercontent.com/pyserial/pyserial/master/examples/rfc2217_server.py
Code:

Did you mean: 'cd'?Then 'mpremote' connecting to the 'rfc2217_server.py' from another terminal session. That got us through to thinking a REPL shell was created, so the handshaking was presumably done, but then 'mpremote' crashed on this 'AttributeError'.
This is Pi 4B 1GB, Bookworm with Desktop 32-bit, Python 3.11.2, PySerial 3.5, 'mpremote' 1.21
That PySerial appears to be the latest version so looks to be a bug in 'mpremote'.
This seems to suggest it's what 'pyb_serial' is set to, but the error does report 'Serial object', so not sure what's going on there -
Code:
Python 3.11.2 (main, Mar 13 2023, 12:18:29) [GCC 12.2.0] on linuxType "help", "copyright", "credits" or "license" for more information.>>> import serial>>> s = serial.Serial("/dev/ttyACM0")>>> s.fd3So you might be able to bump your post up to 'bug report', though not sure if it will help.
