Did you set software flow control in kermit? If either end's on hardware flow control, they may refuse to talk to each other.

Try leaving off -8, I hadn't needed that when I used serial terminals.

Try -l /bin/bash in case the login program is messing up for some reason.

Try just giving it ttyS0 instead of /dev/ttyS0.

Try agetty instead of getty.

If you unplug the cable from the DOS PC, and just bridge pins 2-3 of the serial port with a piece of wire, do you see anything when you type? If your DOS terminal emulator's working at all you should see what you type.

And be sure to hit the enter key on your DOS machine to see the login prompt.

SYSTEMD-GETTY-GENERATOR(8)				      systemd-getty-generator					SYSTEMD-GETTY-GENERATOR(8)

NAME

       systemd-getty-generator - Generator for enabling getty instances on the console

SYNOPSIS

       /usr/lib/systemd/system-generators/systemd-getty-generator

DESCRIPTION

       systemd-getty-generator is a generator that automatically instantiates serial-getty@.service on the kernel console /dev/console if that is
       not directed to the virtual console subsystem. It will also instantiate serial-getty@.service instances for virtualizer consoles, if
       execution in a virtualized environment is detected. This should ensure that the user is shown a login prompt at the right place, regardless
       of which environment the system is started in. For example, it is sufficient to redirect the kernel console with a kernel command line
       argument such as console= to get both kernel messages and a getty prompt on a serial TTY. See kernel-parameters.txt[1] for more information
       on the console= kernel parameter.

       systemd-getty-generator implements the generator specification[2].

       Further information about configuration of gettys you may find in systemd for Administrators, Part XVI: Gettys on Serial Consoles (and
       Elsewhere)[3].
