The last time I got computer parts I threw in a Digilent PmodRS232. That's a MAX3232 on a db-9. A chip that converts from modern GPIO style 3.3v signals to +/-12v RS232 signals for some old-school serial port action. I didn't really need it but I used to do lots of rs232 stuff.
Last night I decided that I could burn a few hours by using it to get the Pi2's serial port out and useable under RISC OS.
