SMS, Packet service and multiplexing

Hi,

After taking a overview of the code, I cannot found how SMS and packet 
service are handled. Using packet service will require some multiplexing 
as I understand.

oFono is by no means a finished product, there are plenty of areas that are 
still not finished, SMS being one of them.  We're actively working on SMS at 
the moment.  Some initial SMS utilities were pushed out yesterday.

Again, this is not yet supported in oFono, patches and ideas are welcome.

I see it now after a git pull. Thanks.

I work on a project where we use a Wavecom modem. We chose to use a 
second serial line to handle the PPP stream. If Ofono have working SMS 
and packet service multiplexing, we will probably evaluate it use into a 
next revision of the project product so we can save a serial line.

Freesmartphone.org does have a 07.10 (27.010) Multiplexer that does the trick of multiplexing.

we are looking at an option to finally put such a multiplexer into the
kernel (where it belongs). The userspace solution generates too many
context switches and introduces latency when we are connecting via EDGE
or UMTS and shuffle a lot of data over that line.

Putting it into the Kernel is a great idea and will improve performance especially when we move to the higher data rates of HSPA. Looking forward to see it.
