I did not look seriously before, but does grub2 have serial support?
I know it does not have PXE or network support. In some ways, grub2
is a regression.

I found this:

Booting from a serial console

If you want GRUB to operate over a serial line, you will need to
uncomment GRUB_TERMINAL in /etc/default/grub and set it to serial
(instead of the console default). The default serial console settings
are to operate on the first serial port (ttyS0) at a 9600 bit/s
transfer rate with 8 data bits, 1 stop bit and no parity.

If you want to use another serial port or if your console uses
different settings, you must add a GRUB_SERIAL_COMMAND line to specify
additional parameters to the serial command. The serial command in GRUB
2 uses the same syntax as its GRUB Legacy counterpart (documented
here). For example, for a 4800 bit/s serial line with 7 data bits, 1
stop bit and even parity:
(the command below should all be on one line. -cybe)
GRUB_SERIAL_COMMAND="serial --unit=0 --speed=4800 --word=7
--parity=even --stop=1"
