LOL, and I guess I should have delved deeper sooner ...

Added : It seems 'pyb_serial' has type 'serial.rfc2217.Serial' which doesn't have any '.fd'
Still adventuring ...
And "Yay!". Wrapping line 41 with 'try: ... except: pass' and -So, leaving that issue for MicroPython to fix properly, the task now is to find what the handshaking send-replies are. Seems that means digging into PySerial itself, or maybe remembering how to use WireShark.
I suspect the answer to your Discussion question will be - Dunno. We simply instantiate a PySerial RFC2217 object and it does all the rest. The source for that is here -

I already had that, is what I used to work out what the Telnet commands were earlier. Couldn't spot where any delivery of acknowledgements was happening. Time to look closer.
