Thanks for the explanation, but what I wanted to say is that the users
expect that the "input/output" buffer in Emacs contains _exclusively_
the input/output text sent to/taken from the process, and in this
case, the process does not write any "\r" character.

In any case, as you said, this doesn't seem to be the origin of the problem.
