Hyperterminal help

Developers/Programmers,

Need help on something very interesting. I need to transfer data using hyperterminal (Windows included version) in real time to MS Access or Excel.
This is to develope a program for air pressure testing station. I have an idea for the program itself (MS access), but can not figure out how to transfer data from hyperterminal to access table in REAL-TIME mode.
I can only transfer data manually by sending it as txt file.
Does anyone know how to do this without paying to buy additional software to take care of this?

Your future help is much appreciated!
