Intel Altera MAX 10 DEV KIT Interface - Can a RS232 6 pin PMOD module by Digilent be used seamlessly with MAX 10 for PC-FPGA UART communication?
@Sid, the referenced PMOD PCB is a level translator. It will convert the CMOS (3v3) voltage levels on the Altera MAX-10 to RS232 compliant voltage levels. Respectively, your PC interface must be also of RS232 levels (NOT 3v3 voltage swings!!) to interface with this PMOD. Having said this, your MAX 10 or whatever FPGA you wish to use must offer 2 GPIO pins for your UART IP. One for TX (transmitter) and another for RX (receiver) to the outside world through this PMOD. You will supply the voltage @ +3v3 and ground from your MAX 10 to power this bridge transceiver and send away. As long as your UART IP is framing at the same speed and format (ie. 9600,N,8,1) using say Teraterm on your PC and your IP is fine on the MAX 10, you will have communication. To keep it simple, DISABLE hardware flow control so that you do not need to wire up the RTS or CTS lines. Check out fpga4fun.com website which details some great Verilog code examples for UART, etc.

@Leon - great to see you here - a true legend and have seen your countless posts and also on the xcore.com forum :)
