I guess that's a good reason to implement as many things in the API. I
do think that you should still leave an option to experiment without
needing to much about frameworkd to add APIs for experiments. The option
to use the 4th MUxer with no GPRS is useful enough for me and my
collaborators.

We need access to the %EM commands. This is useful for an applications
that shows the info to the user. I guess it will be much saner than the
secret sequences you need on various other phones which will be nicer.
The second app is my GSM positioning that needs parts of this
information.

We currently use AT%EM=2,3 & 2,4 & 2,1, I think 2,6 could also be useful
or at least requested by a user.

If we can define an interface I can provide the patch.

I believe we should provide a method for each EM command and return the
fully parsed data. If that makes sense I'll whip up a patch that does
that. I'd consider placing the methods in org.freesmartphone.GSM.Network
