Hi My original comment was in reply to your suggestion of porting Lady Heather into a MSP430. I took that to be your outline of your project. My reply was simply that Lady Heather is a very complex and full featured program. It does *way* more than just look at a serial stream and tell you a few simple things.
If the project has now changed into something else, then so be it.
