I found a way. It seems to work for any kind of device because it just access the devices as a file. See the link android-serialport-api .
It works for any kind of /dev/... In mhy case I had to install the NDK and go through all the hooplas to get it to work. There is a piece of code done in C where it sets the baud rate. In fact, the open and close are implemented in C the rest is all standard android java.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
