[oopic] Serial IO with ooPIC-R

Greetings,

I have an ooPIC-R that I am planning to use to control an audio
installation. The ooPIC will be used to drive a Daisy MP3 player (kit
from Make magazine). I am familiar with RS232C types of serial
connections, but this type of serial IO is new to me. The Daisy has a
serial control interface with TX and RX pins. I will be providing
power to the Daisy using one of the regulated connections on the ooPIC.

This is the diagram of the serial pins on the target device.

My question is how do I wire these two boards together. The grounds
should be linked by the power configuration, but how many other wires
are needed? Which ooPIC objects should I be using? I am just not sure
about timing and flow control.

thanks

-Ray
