On System V you have to create two files in /etc,  /etc/dialups and 
/etc/d_passwd. The contents of /etc/dialups is just a list of the tty ports
you want to provide the extra sequrity for, probably your modem ports. 
One port per line in the file:

/etc/dialups

/dev/tty1
/dev/tty2
.
.
a.s.o.

The contents of /etc/d_passwd is a list of login programs with their
respective passwords.

/etc/d_passwd

/bin/sh:encrypted_password:
/bin/csh:encrypted_password:
/bin/ksh:encrypted_password:

Thus depending on shell,or other program, you will be prompted for an extra
dialup password when you login from a port listed in /etc/dialups. 
The dialups and d_passwd files should then be chmod 444 and owned by root.
