Can you paste the script (or manual commands) that you use before you connect the FTDI serial port to the NAS? Without knowing what it is you're doing, we can't tell what you're doing wrong. Besides using cat, you may need some other software too, to set the serial port parameters such as baud rate and number of data bits, stop bits and parity. ===Jac
