UART1 (only TX, RX signals) is dedicated as a debug port.
The default setting of UART1 is: 115200 baud rate, 8 data bit, no parity, 1 stop
bit and no flow control.
A DB9 null modem cable (or adapter) is required when you would like to connect
UART1 to a PC that runs terminal emulation software such as TeraTerm.
UART0 (with TX, RX, RTS, CTS signals) works as a regular RS232 port.
