Added software flow control but the UART drops characters.

Add ILA into FPGA to better understand why.

Using 2 stop bits fixes the corruption on a byte level, seems the UART has bug(s)?

XON/XOFF is hopeless due to 4K buffers in the FT2232H used on the Arty A7 Dev Board. I think you can reduce the FIFO depth on it, so that's the next option.
