Boolean operations on strings

I am using Real Time Serial Read to read serial communication from an Arduino. I want to perform boolean operations on the received string for further processing, but it seems that Embed does not support direct boolean operations on strings. What should I do? Do I need to convert the string to binary first, or is there a faster way? If I need to convert the string to binary, how can I do that? Alternatively, are there any other better ways to perform boolean operations on strings?

Thank you for your response. It will be helpful to me.
