The convention for dealing with the prompt is that you

Thus the last thing that a procedure does with the serial line
will be an gr_expect_prompt(). Exception: resume does not
wait for the prompt, because the terminal is being handed over
to the inferior. However, the next thing which happens after that
is a bug_wait which does wait for the prompt.
Note that this includes abnormal exit, e.g. error(). This is
necessary to prevent getting into states from which we can't
recover. */
