Well this project seems to be dead. Anyway for what it's worth, the
problem turned out to be some difference between the AT+CMUX behavior
betwene the sim900 and the sim5320 module. When I tore out all the MUX
related code the 3G / internet / ppp aspects all just start working.

Hello, I'm at my wits' end trying to get ofono working with
sim5320 module. I'm using the plugins/sim900.c module as a starting
point. I think the issue has something to do with the difference
between the MUX functionality between the 900 and the 5320.
