Still no luck, but I think I've ruled out serial settings. I connected a logic analyzer to the TX/RX pins 15/14 and used a UART protocol decoder set to 19200 baud 8N1. I see three bytes on the wire, CR, R, E which is the same as I see in the terminal. zqBLSKfx.png To me, this means that the circuit from the DE-10 through the I/O board to the FTDI a...

I've done the following, Added headers to the I/O board so that JP2 of the DE-10 Nano (TX, RX, GND) pass through to the USB user port on the I/O board Constructed a USB cable to attach the TX, RX and GND lines to an FTDI board C...
