Default Serial Console
----------------------
UART0 is configured as the default serial console at 115200 8N1
on pins PE0 and PE1.
LEUART0 is configured as the default serial console at 2400 8N1
on pins PD5 and PD4. It certainly be possible to go to 4800 baud
and the documentation claims that 9600 baud is possible (although
I am not sure how).
It should also be possible to use UART0 is configured at 115200 8N1
on pins PE0 and PE1. However, my attempts to use USART0 were
unsuccessful -- I see no activity on PE0 and PE1 and have not yet
figured out why that is.

Configures the NuttShell (nsh) located at apps/examples/nsh. The
Configuration enables the serial interfaces on UART0. Support for
built-in applications is enabled, but in the base configuration no
built-in applications are selected (see NOTES below).
Configuration enables the serial interfaces on LEUART0 at 2400 8N1.
