|
|
The convention for dealing with the prompt is that you
|
|
o give your command
|
|
o *then* wait for the prompt.
|
|
|
|
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. */
