Hello everyone! Thanks for all of your patience. We are currently working hard on trying to get our new touch screen out the door. This is requiring some minor changes in the ElkRM software. I just wanted to make everyone aware that the new version of ElkRM (when we release it) will require the .NET framework version 2.0. The new framework allows easy control of the serial port on your PC. Yes, the next version you will be able to use your serial port to connect. Thanks for everyones support with this software, your feedback will only make the product better!
