So I'll be using some GPIO pins and a breakout to make a serial port that I know for sure how it works. With my bus pirate, I can see traffic from the uart on the right pins, but somehow that doesn't actually appear on the db-9 connector at the edge of the board, and hence doesn't reach the PC.
Partly because I'll need them for the final target FPGA board, and partly because the dev board I do have seems to have something strange with the serial port. I've decided to learn how to etch my own boards, and make a little breakout PCB for the serial, VGA and PS/2 connections. Things have slowed down a little with the terminal - partly due to the need to actually create something physical next.
