Hey Matt,
the above wiki page does not say much. It does not answer the questions I have
asked and also the test results "OK" does not say much for incoming call/sms.
What I miss from the tests:
- The the setup is not described. Was gsmd used. Was minicom used? Which
kernel version, which hardware revision, which firmware revision was used to
do the test? This is like physics one describes the setup of the experiment.
- How was it tested? Was the device put to sleep with echo "mem"
to /sys/power/state
- Then the device was called /sent a SMS to and it woke up?
- Where is the log file of the modem communication. It would be nice to have
an annotated version, where you annotate where the device was suspend and
when it was woken up.
Reasoning of experiments/tests:
One wants to verify a hypothesis.
You create a setup (a test) and then you do the testing.
You do the test and keep a log
With software you redo the test after fixing the software
While developing ideally each of these things will be a regression test,
sometimes this is not feasible.
Main Reason for experiment/tests:
Other people can verify the results and people start to trust the results of
an experiment/test.
Back to the point:
My modem is waking me up immediately, I have described my test in the initial
mail (I didn't name the version numbers). The result doesn't match the result
on the wiki page and I want to find out why.

PS: Allen's test plans looked good on a first sight :)
