Hello Dan, Is ModemManager baud rate configurable to a different value? I know that by default ModemManager runs properly with modem baud rate set to 57600.

I appreciate your help very much. You need to install neccesary build dependencies for your chosen architecture too. Looks like you're missing glib and its associated libraries for ARM installed in the cross-compile library directory.
