Ioannis,

I was assuming that not all of the bytes would be in ascii, I have a device that I communicate with that sends ascii labels like "b=" and then sends hex values as the variables change. That's why I suggested that he might want to send the buffer[3] byte out to an lcd, just to make sure. I know I went nuts testing with hyper-terminal, because it kept taking the hex values and converting them to ascii characters and printing out nonsense.
