I think I understood.
I'm buying a RS232 Null Modem cable.
In ubuntu 9.10 there is not /etc/inittab. Init reads the command to execute by files in the /etc/init directory. However i think i will resolve.

Thank you again for your instructions!

Ps: If i'll have problems, i'll edit this post. Thanks again!
--------EDIT---------
I have a problem! In the DOS kermit client i don't see login prompt and no activity!
Here is my configuration. In both computers I have one serial port, db9 (9 pins). I connected the 2 pc with the null modem cable. I started kermit on the DOS pc. I setted no parity (set parity none). I setted 1 stop bit (set stop-bit 1). I setted 8 data bit (set term byte 8). port com1 (set port com1). baud 9600 (set baud 9600). set flow-control xonn/xoff. And finally i connected (connect).
In the shell of desktop ubuntu pc i typed: 'sudo /sbin/getty -8L 9600 /dev/ttyS0 vt320'
(vt320 is the model of emulated terminal). The command just hangs... And i dont see any login prompt on the dos pc. No garbage, nothing at all.

I tried a lot of times, but i'm not an expert... How can I do?

Thanks for any answer!

TERM(1) 						      General Commands Manual							   TERM(1)

NAME
term - turn PC into a dumb terminal [IBM] SYNOPSIS
term [baudrate] [parity] [bits_per_character] [-dial_string] [device] EXAMPLES
term 2400 # Talk to modem at 2400 baud term 1200 7 even # 1200 baud, 7 bits/char, even parity term 8 9600 /dev/tty01 # 9600 baud, 8 bits/char, no parity, use tty01 term -atdt12345 /dev/tty01 # Start with a command to dial out DESCRIPTION
Term allows MINIX to talk to a terminal or modem over RS232 port 1. The program first sets the baudrate, parity and character length, and then forks. The parent sits in a loop copying from stdin (usually the console's keyboard), to the terminal or modem (/dev/tty00). The child sits in a loop copying from the terminal or modem (/dev/tty00) to standard output. Thus when RS232 port 1 is connected to a modem, every keystroke typed on the keyboard is sent to the modem, and every character arriving from the modem is displayed. Standard input and output may be redirected, to provide a primitive file transfer program, with no checking. Any argument that starts with a minus ('-') is sent out to the modem, usually to dial out. Term accepts several commands that are formed by typing the escape character, CTRL-], and a letter. Type CTRL-]? to see a list of commands. The subshell command is very important, it allows you to type in a ZMODEM command to transfer data. Do not quit term to do this, or your modem line will be reset! Term keeps the modem line open on file descriptor 9 while running the subshell, so you can type <&9 >&9 at the end of your ZMODEM command to connect it to the modem. Important note: to use term, it is essential that /etc/ttytab is configured so that there is no shell hanging on /dev/tty01. If there is, both the shell and term will try to read from /dev/tty01, and nothing will work. SEE ALSO
