+         Select this to enable a seral UART for sandbox. This is required to
+         operate correctly, otherwise you will see no serial output from
+         sandbox. The emulated UART will display to the console and console
+         input will be fed into the UART. This allows you to interact with
+         U-Boot.
+
+         The operation of the console is controlled by the -t command-line
+         flag. In raw mode, U-Boot sees all characters from the terminal
+         before they are processed, including Ctrl-C. In cooked mode, Ctrl-C
+         is processed by the terminal, and terminates U-Boot. Valid options
+         are:
+
+            -t raw-with-sigs   Raw mode, Ctrl-C will terminate U-Boot
+            -t raw             Raw mode, Ctrl-C is processed by U-Boot
+            -t cooked          Cooked mode, Ctrl-C terminates
