The Serial-HOWTO has some information on that.

As a terminal, you mean you want to be able to log on to it over
serial (sorta like you use telnet over ethernet)?  If so, go to
/etc/inittab and add:

S2:2345:respawn:/sbin/getty ttyS2 115200

replacing 115200 with whatever speed you are running the port at.
