I have a widget that I want to give a login process from my mac's usb port through an ftdi chip. I know that in Ubuntu, I can add something like:
start on stopped rc RUNLEVEL= stop on runlevel [!2345] respawn exec /sbin/getty -L 38400 ttyUSB0 vt100
to my /etc/init/tty.USB0 file.
Is there an equivalent way to do this in osx?
