Do you have a picture of these points ... I would be curious to see what it show on serial port
Like I said, I haven't tried this on the new design. On the original #11 the points were situated at the edge of the board next to the processor. On the new design there are three points, instead of four, next to the processor. These look suspicious and could well be TX, RX and GND. If you have a TTL to RS232 converter you could try hooking up the TX (I'm sure it's one of them) and a ground point.
