I am using UART1 RS232 port to communicate how Linux console and it works properly.
How to enable the UART2 232 for exchanging data? (Open, read, write and close).
What I have to modify the kernel and in which file?
There are commands that I can give directly from the console to test the port, read and write? (Type cat / dev/ttymxc2 or echo> / dev/ttymxc2?)?
