How to make many buttons work in parallel?

I am developing a windows application in C# where I need to communicate with a microcontroller through the USB. This application has a button that sends code to the microcontroller through the USB, one that sends the microcontroller to pause which it is running and has another one that tells the microcontroller to stop what it was doing.
When I press the send button it works normally, the problem is that while it is running to click on other buttons do nothing, because the send button will only release the running for the other buttons after it has finished all the code that it has in your body. I need that the pause and stop buttons also work while the send button is running.
I think that I may be able to do this using threads, but I do not know much about threads. Does anyone know how I do it?

Thanks in advance.

Does your micro-controller support any hardware interrupts ?

My application does not interrupt the micro-controller, pause and stop buttons only send one line of code in which the micro-controller knows whether stop or pause the action that it is running.

If you don't know much, this is useless. Learn it. Look at your talking. Buttons do not work in parallel, processors, processor cores and threads do.

The problem is (probably, without seeing your code it is mostly guesswork) that your button handler does not finish as quickly as possible - so the UI task does not get to do anything such as respond to a mouse event until it has. Your only real option there is to use a thread and move the processing code out of the UI completely. You could probably do this quite easily with a BackgroundWorker[^] - the link includes an example of starting and cancelling a thread.
