It is better to enable the hardware uart, reboot and ensure you have /dev/ttyAMA0 and nothing is using this port already, then it should work fine talking to the arduino.
Sean,
For some reason I was under the impression it should be /dev/ttyS0. I'll give it a try as soon as I get the hardware back together. Should be done this weekend. What optocouplers do you recommend?
Thanks for the help.
I am using cpc5001 opto isolators but others may work.
