98 The convention for dealing with the prompt is that you
100 o *then* wait for the prompt.
102 Thus the last thing that a procedure does with the serial line
103 will be an gr_expect_prompt(). Exception: resume does not
104 wait for the prompt, because the terminal is being handed over
105 to the inferior. However, the next thing which happens after that
106 is a bug_wait which does wait for the prompt.
107 Note that this includes abnormal exit, e.g. error(). This is
108 necessary to prevent getting into states from which we can't
