Descriptions
The BeagleBone RS232 Cape provides an RS232 interface to the BeagleBone via a
standard D-Sub 9 female serial connector. This connector is located to the side so it
doesn't interfere with any capes stacked above it. By default, the BeagleBone RS232
Cape uses UART2 port on the AM335x for RS232 connection; however, users will have
the freedom to choose among UART1, UART2, UART4, and UART5 ports.
