How to get SARA-U201 EVK working on Ubuntu 16.04

0 votes
Hi, I'm trying to get the EVK for SARA-U201 connected to Ubuntu 16.04 by either USB or RS232, I'm getting to a stage where ttyUSB0 is online, but I can't enter commands, and for the same reason no replies are ever shown. LD403 is lid up green when the USB is selected by the switches SW401 and SW403, and DL501 is lid up blue so I assume the cable is properly connected and switches in the right position.

The final goal for my project is to get the device connected and registered in Linux as a network interface. Any help regarding this is very welcome.

The appropriate Linux drivers for SARA should be available from most Linux driver source servers.
Refer to the SARA System Integration Manual for details on how the ACM port functions are allocated and if they can be changed.

How do you make the device show up as a ACM port device?  

I get this in syslog when I power on the dev board:
