However I am sure the serial pins are there somewhere.

There are somewhere on the right side. There is a row with 12 contacts and one with 11 contacts. Try to find all ground pins. Then probing and find with an oscilloscope the tx pin (uart 2.6V-3.3V signal), check for voltage before connecting.
Look at the ground pin which is close to the determind tx pin. Probably one of the neighbour pins (from ground) is the rx pin, which should be also close to the tx pin maybe one mbus signal in between. The neighbour pin could also be diagonal to the other row. Rx and tx pin should reside on the same row with this kind of two row pattern.

Or ask some developer on irc or mail. I would suggest rainisto or pali.
