I have a Lawn watering system that runs on my computer. The watering system sends a string of data to a COM Port that has a device plugged in; this device is called a Firecracker. The Firecracker sends a signal (via RF wave) to another device that activates the watering valve.
I would like to write a new watering system using MS Access. I think I know how to put the system together but I don't know how to send the required data string to the COM Port (Firecracker) that will ultimately control the watering valve(s). I'm looking for help creating the code required to get MS Access to talk to the Firecracker.
Any help offered will be greatly appreciated.
Thank you, Greg Good
