gsm shield2, UART

Hello everyone,

have somebody tried to readout from the debug interface (dtx, drx)? I only get unreadable data, even if I set the Baudrate to 460800 like it's described in the documentary.

docs: https://www.arduino.cc/en/uploads/Main/Quectel_M10_datasheet.pdf
Details about the Baudrate are on page 46.

I appreciate your help!
