Data transfer between Cyclone V GX Starter Kit and PC

Hello, FPGA newbie here. I'm trying to create an interface between my PC and my Cyclone V GX Starter Kit (https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=165&No=830&P...

    PI'm commonly using 920 kbaud UART interface between PC and FPGA for test and configuration tools because it's the fasted standard rate supported bei PCs or e.g Bluetooth adapters. Non-standard RX oversampling factors, e.g. 13 instead of 8 or 16 are helpful to operate the UART with usual clock frequencies like 24 or 48 MHz.

    P.S. Forgot to mention that FT232R supports up to 3M if you need higher speed, but it needs special programming on the PC side to set the non-standard rate. FTDI has suggestions how to achieve it.
