[Java] Sending String to screen session

Thu Aug 03, 2017 8:30 am

Folks,

I'm trying to do the task which will use the Java on Pi 3 to do serial talk to an external device.

But I just have no idea.

I know Java has Process object which I can invoke exec(String[] cmd) so I should run exec("screen", "/dev/ttyUSB0", "9600") from the main method.

The part I have no idea is to flushing some String into that screen session so the device can interpret the String further.

Thanks in advance for any suggestion.
