I need to import data from blood glucose devices into my VB .NET / C# application. I'm going to start with the Accu-check lineup. I ordered the "universal cable". This "universal cable" is more like a hub, where blood glucose devices can hook into. The "universal cable" hooks directly into your computer via serial port. Communications on my machine is done through com port 1. I installed the Accu-check program, which was done in Visual Basic 6.0 and this program communicates with any Accu-chek device. It also allows you to update the current date/time that is within the device. So it also sends data to the device. I need to do this, but I can't even start this. I'll move this to the Computers/Programming forum in a bit.
