Perfect. Thanks so much. The program is now working and is receiving the data from my microprocessor. I knew it had to be something simple and it was driving me crazy.

Honestly, I didn't know where to look for documentation for this problem so knowing to check Microsoft's MSDN site is very helpful. I'm used to all my devices having datasheet for each piece of hardware. I'm still new to my software side. Anyway, knowing where to look now, I found the link you were referring to as well as the note you mentioned:

SerialPort.DataReceived Event (System.IO.Ports)

Thanks again!
