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.

TTYTAB()																  TTYTAB()

NAME
ttytab - table of login terminals SYNOPSIS
/etc/ttytab DESCRIPTION
The ttytab file lists all the terminal devices that one can login on. It is a simple text file that contains lines of the form: name type "getty" "init" The name and type fields are simple words, name is the name of the terminal device with /dev stripped off, and type tells the type of ter- minal to initialize the TERM environment variable. The getty and init fields may name commands that are run to allow one to login on the line, or to initialize the line. Both these fields may be more than one word if the whole field is enclosed in double quotes. Getty is usually simply the word getty, the command that prints a system identification banner and allows on to type a name to log in. Init is usually an stty command to set the baud rate and parity of a serial line. The init field may be omitted to indicate that no initialization is necessary, and the getty field may be left out to not start a login process. Terminals should not be left out, because their place in the ttytab file determines their slot number as returned by ttyslot(3). Comments (introduced by #) and empty lines are ignored. EXAMPLE
A ttytab for the console, two serial lines, and a pseudo tty entry: console minix getty tty00 vt100 getty "stty 9600" tty01 dialup getty "stty 38400" ttyp0 network ENVIRONMENT
TERM Terminal type NOTES
It is customary to set the type to dialup for a dialin line. One can check for that name in one's .profile. SEE ALSO
gettyent(3), ttyslot(3), init(8). AUTHOR
