I have an ELM327 device with a USB connection and drivers.
I am looking for a Good article or guide to teach me how to use hyper terminal to communicate with obd2 vehicles and send commands and receive data?
Another good alternative is PuTTY. http://www.chiark.greenend.org.uk/~sgtatham/putty/
They just added serial port support last January. I never liked using Hyperterminal much and I have been using PuTTY for years as my telnet client.
While I've have to use Putty via SSH when in need of free software, I'd never use it voluntarily if I had another option - and my other option has always been SecureCRT.
But heck, it works and it's free, so two out of 3 ain't bad.
