I am crafting C util to read data from tty00 (amd64, i386; connected to the data src device directly by serial cable).What should I put in /etc/ttys for the tty00 to make sure I am doing things correctly? The util is to be run as root.
you don't need to edit /etc/ttys, your C program has to open /dev/cua00 (not /dev/tty00) and everything will just work.
