Supported Platforms: MODM7AE70

Demonstrates how to open all available serial ports on the MODM7AE70. There are a total of 7 named SerialPort 0 - 6, which correstpond to USARTs 0 and 1, and UARTs 0 - 4. Note that the difference between a USART and a UART is that the UARTs can only be used for regular serial with TX and RX signals. The USARTs also include hardware handshaking, can be used for RS-422/485, and support other serial modes such as SPI.
