Hope this helps
Well my debug board shows only one serial port (ttyUSB1) .... :( Well I think there is some hardware problem because I remove fpc cable from the GTA02 still I am getting special charactors on my computer minicom so I thing fpc cable is catching some noise as TX and RX tracks are so close. Other thing I have found that GTA02's TX signal is not comming on the board.
