I have a USB-to-Serial converter for my Mac I want to use to connect to an Ubuntu server that outputs all its console over its serial port (it's an APU2 machine with no graphics output). On the server
/etc/default/grub contains the following lines:
GRUB_CMDLINE_LINUX="gfxpayload=text fb=false console=ttyS0,115200n8" # Uncomment to disable graphical terminal (grub-pc only) GRUB_TERMINAL="serial" GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1"
The USB-to-Serial shows up as
/dev/tty.usbserial on my Mac. What do I state the port # as in grub?
