* open the Terminal application
* connect the DM unit
* put the unit in terminal mode: [c]+[on]
* start a console session: screen /dev/tty.SLAB_USBtoUART 38400,8,n,1
* the DM unit menu is now active (press ? for help)
* put the unit in normal mode: [enter] (or any other key)
* end the console session: press [CONTROL]+[a] then [k] then [y]
* disconnect the DM unit
