So I'm running W7 and as I'm sure many of you know, MS ditched hyperterminal after Vista. This leaves a bit of a void in my life as it can be difficult to communicate with micro's from my PC. Normally I would just use Matlab for communication as Mathworks makes it rather painless but it can be a pain in the ass to work with sometimes. And every time something goes wrong or I want to re-establish communication, I have to restart Matlab. In Excel 2003, I have used the MSComm1 command and the VB.NET API to communicate through serial ports. Well, now I have Excel 2007 and 2010 and I can't find a dam thing about how to communicate to COM ports with them. Does anyone have a clue? I've seen some stuff out there using Active X for communication but it involves dealing with the registry and looks way to dam confusing.
