At least, we have fixed the prompt problem :-)

Your shell on the remote side cannot suppress echoing the sent
command. Therefore, Tramp applies some special workarounds.

Surprisingly, your remote shell stops to echo the sent command. Tramp
looks for the echo, and is confused ...
Could you, please, test the appended fix?
Best regards, Michael.
