Most dev boards have a serial connection as well as the USB blaster. Usually these are an FTDI or similar serial to USB converter chip. Connect a USB cable from that port to your computer. The port will usually show up in the linux /dev directory. Hint: Do "ls /dev" before and after connecting the cable. The entry that appears when the cable is connected is your serial device. Use standard linux seral port programming from there. Another hint: The command "stty < /dev/<whatever>" will tell you the baud rate etc that the port is set to.
