I have a script which takes real-time input from an external device. The script begins with establishing a connection to this device, then does some real-time data processing and ends with shutting down said connection. I would like to be able to gracefully terminate the script by user input, that is have the script stop what it's doing, run the shut-down procedures before terminating completely. Currently, I can press ctrl+c to terminate the program, but this causes errors on subsequent attempts to reconnect to the device.

What I have done in a GUI is adding a button that is only visible when a callback is active. Each iteration of the loop I first check if the button has been clicked, if so, I exit the loop.

Rik provided a nice solution. If you do not have a GUI you might be able to use my STOPLOOP function in your code (which creates a very simple GUI itself): https://uk.mathworks.com/matlabcentral/fileexchange/20455-stoploop--v1-0--jun-2008-
