nothing substantial right now. If the modem manufactures only give you
text SMS and non-PDU STK, then we have some serious problems. oFono's
internal core talks only PDUs. You would have to do multiple level of
conversions to get oFono work with your hardware.

Personally I think the interface of your CDMA hardware is broken and
should not be used at all. The fact that nobody got text SMS into any
kind of consistent state and every single firmware out there has a
different bug is a huge problem for us. oFono has to work with every
single piece of hardware.

I thought that the pure binary interfaces like ISI are a challenge, but
that is nothing compared to what you are facing :(
