For h/w flow control, you need to check if the CTS and RTS signals are being brought out to the serial header on the beagle-board. Looking at the schematics for the 3430 beagle board, it appears that only the UART RX and TX signals are available on the serial header. Therefore, I don't believe you can test h/w flow control using the console with that board. I do see that you can access all the UART2 signals (RX/TX/CTS/RTS) via the expansion connector on the beagle. However, to connect to a serial port on a PC you need to have a voltage level-shifter in-between. There are some companies out there that make them [1], but you need to make sure you have one that can support a 1.8V input.
