BGS5 based proto unresponsive | Telit Cinterion IoT Developer Community

We created a prototype board with a BGS5. It is supplied with 3.5V. The igt (on) signal is triggered, 300ms after power on. 

We do not see anything coming out of ASC0.

USB does enumerate, but only 1 device, installs as modem. When connected to this usb modem's com port with realterm, it does not respond to anything.

Any advise on how to proceed would be very much appreciated.

After carefull review of the hardware, we did notice 1 thing: We connected pin 98 to ground, but hardware description states : do not use.
Can anyone please give more info on this pin 98?
Could this connection to ground be te reason why the module is not responding?
