Please tell me: with gsm0710uxd the connection is still done by 
pppd/chat?

I hope to last 12 hours or so, because I do GPS live tracking 
with position upload to the internet every 5/10 seconds.

But the real problem is that if the connection fails, it will not 
restart again. I can add a cronjob to test connection and restart 
it, but I know that pppd should manage the fault.
