Acronyms
========
MDK is, of course, the Motorola Development Kit.
MuC is the acronym that is used to refer to the STM32L476ME on the MDK
board.
MHB is the acronym given to Toshiba Interface Bridge, part number T6WV7XBG.

You may need to be super-user in order access the /dev/ttyUSB2 device. The serial terminal that you use must be configured to use the /dev/ttyUSB2
device at 11500 baud, no parity, 8 bits of data, 1 stop bit (115200 8N1 in
minicom-speak) and with no flow control. Minicom works well.

The Motorola documentation also mentions picocom. NSH also works well with
picocom:
$ sudo apt install picocom
$ sudo picocom -b 115200 /dev/ttyUSB2
Everything else defaults correction. Ctrl-A then Ctrl-X will terminate
either the minicom or the picocom session.
