Jon, 

Thanks I actually just downloaded the RS232 pdf guide about 30 min
ago off the web. It seems like its a great guide. My hardware 
configuration is exactly as shown in the guide. I'll try the codes and see
how that works. 

Eric:
Maybe I'm not understanding your question, but take a look at the pdf file 
Jon posted page 19 line code 7.
