Check out mgetty and initab. mgetty has documentation. It tells you to add lines to initab
I installed mgetty and added the following lines to initab

# modem getty.
mo:23:respawn:/usr/sbin/mgetty -s 57600 /dev/ttyS0    <-- serial port connected to modem which is connected to phone

When they logged in my own bash shell script handled the login. It was called bbs_login and was stored in /etc/skel so that when a new account was created my shell script was put into the home directory, and run instead of bash.
