hardware serial rather than USB

[jakobbak]

Hello All

Apologies for asking a question that may seem trivial, but I haven't been able to find an answer here or in the forks I was able to examine.

I was hoping to be able to use the serial interface, but over normal serial pins rather than USB. Are any of the existing pins available on the board attached to a serial peripheral? I realise I'll probably have to write up the serial handling myself, and happy to give that a shot, but in case there is another project that has done the same I'd be happy to take a pointer to such a project :)
