I also ran into this issue in 2.06, trying to set GRUB_TERMINAL="console serial_com1 serial_com0". I'm also not sure how to configure multiple serial consoles with GRUB_SERIAL_COMMAND, I tried setting it to two separate serial commands separated by a semicolon, like:

GRUB_SERIAL_COMMAND="serial --unit=1 --speed=115200 --word=8 --parity=no --stop=1; serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1"

Not sure yet if this works.

Under Gentoo Linux with sys-boot/grub-2.02_beta2-r9 I get this error:

With


GRUB_TERMINAL_INPUT="usb_keyboard0 serial_usb0 console"
GRUB_TERMINAL_OUTPUT="serial_usb0 console"
GRUB_SERIAL_COMMAND="sleep --verbose --interruptible 1; serial --speed=115200 usb0"
GRUB_PRELOAD_MODULES="nativedisk ehci ohci uhci usb usbserial_ftdi"


in /etc/default/grub you get:


# grub2-mkconfig -o /boot/grub/grub.cfg
Invalid output terminal "serial_usb0 console"


This can be fixed by changing /usr/sbin/grub2-mkconfig from


for x in ${GRUB_TERMINAL_OUTPUT}; do
    case "x${x}" in
        xgfxterm) ;;
        xconsole | xserial | xofconsole | xvga_text)
            # make sure all our children behave in conformance with ascii..
            export LANG=C;;
        *) echo "Invalid output terminal \"${GRUB_TERMINAL_OUTPUT}\"" >&2 ; exit 1 ;;
    esac
done


to (note the appended * after xserial)


for x in ${GRUB_TERMINAL_OUTPUT}; do
    case "x${x}" in
        xgfxterm) ;;
        xconsole | xserial* | xofconsole | xvga_text)
            # make sure all our children behave in conformance with ascii..
            export LANG=C;;
        *) echo "Invalid output terminal \"${GRUB_TERMINAL_OUTPUT}\"" >&2 ; exit 1 ;;
    esac
done


But now the GRUB_SERIAL_COMMAND isn't added to grub.cfg because of the following lines
in /etc/grub.d/00_header


for x in ${GRUB_TERMINAL_INPUT} ${GRUB_TERMINAL_OUTPUT}; do
    if [ xserial = "x$x" ]; then
    serial=1;
    fi
    if [ xgfxterm = "x$x" ]; then
    gfxterm=1;
    fi
done


After changing these lines to


for x in ${GRUB_TERMINAL_INPUT} ${GRUB_TERMINAL_OUTPUT}; do
    case "x${x}" in
    xgfxterm) gfxterm=1;;
    xserial*) serial=1;;
    esac
done


now


# grub2-mkconfig -o /boot/grub/grub.cfg


creates a valid and working config.
