Jonny and Bean,

Thanks for all the help.  I went back and studied the hardware on the chip and found that even if the port is configured as an output, you can read its state.  I found my biggest problem was with my reference voltage.  I used a 10K pot and adjusted it until I got the state change to occur at the right time. Now, I may even try to use edge triggering which I had tried before and found it failed.
