+//! <h1>UART Echo (uart_echo)</h1>

+//!

+//! This example application utilizes the UART to echo text.  The first UART

+//! (connected to the FTDI virtual serial port on the evaluation board) will be

+//! configured in 115,200 baud, 8-n-1 mode.  All characters received on the

+//! UART are transmitted back to the UART.
