Hi Bill,

I am using VB Express to read data streams from COM1. The data is from a datalogger (Aqualog). I have a windows application that displays live data and enables settings to be changed on the fly. It also uses MS Access for a database. The data can then be displayed using Excel. All this is very easy to do.

And if you have MS Office it is all free when you use VB Express. I also downloaded SQL Express for free.

Wind direction sounds interesting and I will have a look into this.
