Getting Data from Serial Port using Comm Control
If you want to be professional about it, I would go with a neat little
data aquisition device from Black Box, model# SDA232 (SDA=Serial Data
Aquisition). I have used this device in several applications. It has
8 Analog Inputs, 3 digital Inputs, and 3 digital Outputs, and costs
about 88.00 including shipping. You can check out the specs on the
product at http://www.blackbox.com
Have fun :)
