I've successfully connected to the B190 via serial. The pins for Tx and Rx can be found at imgur /a/XA5Ad

When connected and booted, you get dropped into a VxWorks shell.
It's the first time I've seen this OS, so I'll need some time to find my way around.

I'm able to browse through the filesystem, but it contains mostly binary files (executeables?).
Next, I'll try to extract the firmware.

Maybe some of you have experience with VxWorks? Do you know any way i can communicate with the modem through this shell? My goal is still to issue some AT-commands or find a way of unlocking the modem.
