I think I need more accurate meter here. My old Fluke 23 is only 3 1/2
digits and don't have needed resolution. I believe that suspend mode is
failing to turn off some of the hardware in my case. I have not upgraded
the firmware on my GSM module. Because the SSH connection between the
Neo1973 and the host PC is dropped when the Neo is suspend I will need
to connect the serial console to see the messages. Do I need to do
something special to enable debug messages on the serial console or just
connect the debug board?

Thank you Psi,
