Login as root, then:
        cd /etc
        mv inittab inittab.old
        elvis inittab

Within elvis type:
        ittys1:vt200:/etc/getty 9600 ttys1<ESC>ZZ

Note the small 'i' at the beginning which places elvis into insert mode. You
will also probably have to change ttys1 for your serial port (COM1 = ttys0,
COM2 = ttys1 etc.). The 'ZZ' at the end write everything into the file and quit
elvis.
Then you have to activate the new inittab by:
        kill -1 1
or simply by rebooting (which is probably better).

I think this could be done without a screen. Don't forget to connect DCD at
the serial port. Otherwise getty can get a SIGHUP.
