serial output startup

HI,

Me again, trying to get deeper and deeper into the firmware.. understanding only a little..

Now I found a way to see the serial data at 115200 Baud.. 9600 no result.
Most of the time the dail is working, missing now and then a digit.

But something is wrong with the LARA, see attached serial output during startup..
I have my SIM of Telekom Germany installed, no SIM lock, no Pin ..

Can somebody comment what is wrong...?

I also want the Bell to work, at least to test it... but no 3+alpha or 3+ function or any other combination works...

Also here ..somebody more lucky..?

Thanks,

Roel

And when i Connect with Putty i do not get any responses back from the arduino…

Any AT command are Not responsive..
Is something wrong with the LARA..?
Does it react Even when the sim is Not working..?

Lots of questions..
Is there somebody out there..where this works..?
