right.
let me explain what I did.
I am newbie in Linux but not in programming.
So,
I have a code which is working on Linux system. I changed the tty
(console) to /dev/ttyAM1 and ttyS0 to /dev/ttyAM0.
I run the code on the Board, it works with a device which sends data
over serial port but when I connect my cell phone it doesn't work. I
mean serial_IO_handler isn't called ? I wanna know how
serial_IO_handler is called(I mean changes on serial pins).
Hope it is enough.
