+ * Selects the behavior of the serial terminal.

+ * If Ctrl-C is processed by U-Boot, then the only way to quit sandbox is with
+ * the 'reset' command, or equivalent.
+ *
+ * If the terminal is cooked, then Ctrl-C will terminate U-Boot, and the
+ * command line will not be quite such a faithful emulation.
+ *
+ * Options are:
+ *
+ *     raw-with-sigs           - Raw, but allow signals (Ctrl-C will quit)
+ *     raw                     - Terminal is always raw
+ *     cooked                  - Terminal is always cooked
