You'd need to use VSTO (Visual Studio Tools For Office) SE to create a
NET-enabled workbook or add-in, and from there you'd be able to use
the NET BCL. You can't use NET directly within an Excel workbook.

There is a product called WinWedge that is an excellent tool for both
sending and receiving data through a serial port from an Excel
workbook. For more information please visit: www.taltech.com
