How can I figure out an unknown UART's speed?
So I have a piece of hardware I'm reverse engineering. I believe I've found a UART on the board. I have an FPGA connected to it that just does:
ExtTX <= PCRX;
PCTX <= ExtRX;
So, in this way I can theoretically handle any speed the FTDI on my FPGA can(which is fairly fast). So, I have the hardware portion covered. Now though, using Linux(or Windows), how can I figure out what the speed and stop bits and other configuration options of the serial connection should be?
