I have a simple serial device that I need to talk to (but not listen to) periodically via command.
The device is connected OK as /dev/usbxxx.
What is the simplest/easiest way to do this?
Installing software (python, minicom, whatever) is fine.
The exact scenario is I have an Arduino device (a Cube4) that I want to use as a build light. Periodically, I will poll the CI server or use RSS etc and need to tell it what color to display. Using session-based solutions (like screen) seems like they won't work because the terminal command runs elsewhere (although I suppose I could remote to the screen session, send the chars via who knows what, then disconnect).
