114 The convention for dealing with the prompt is that you
116 o *then* wait for the prompt.
118 Thus the last thing that a procedure does with the serial line
119 will be an gr_expect_prompt(). Exception: resume does not
120 wait for the prompt, because the terminal is being handed over
121 to the inferior. However, the next thing which happens after that
122 is a bug_wait which does wait for the prompt.
123 Note that this includes abnormal exit, e.g. error(). This is
124 necessary to prevent getting into states from which we can't
