Hello,

Let's say, I have the following output in response to sent command:

=============================
DEVICE | STATE
=============================
LKS1 | ON
LKS2 | ON
LKS5 | ON
LKS6 | ON
-----------------------------

I'd like just to collect info about these "LKS".

There is a good recognizable "device entries" and "end of output",
definable by regular expressions.

How could the expect repeat "expecting" (and "stop expecting", when "end of
output" has been reached)? I used exp_continue, when recognizing the device
entry, but expect ate up one entry and gave up, though.

Of course, an alternative way is to look over the expect_out(buffer), but
I hope there is an easier way to do it.
