Sending Ctrl-Break with screen and USB Console cable

The USB tty device shows up on my machine as /dev/tty.usbserial-AL00LNQH

I recently needed to send Ctrl-Break to boot a Cisco router to rommon, but as MacBook’s don’t have a Break key I wasn’t sure how to accomplish this.

This serves as a reminder for myself that you do this by pressing Ctrl-a and then Ctrl-b
