Three steps:
1) See if your version of login supports dialup passwords:
#strings /bin/login |grep d_pas
/etc/d_passwd

2) Create a /etc/dialups file containing the name of the tty you want to guard:
#-r--------   1 root  root   189 Nov 24 08:46 /etc/dialups

/dev/tty500
# /etc/dialups will contain all of the devices that
# **might** present Dialup Password, depending on 
# entries in /etc/d_passwd.

3) Create a /etc/d_passwd controlling all possible login shells:
#-r--------   1 root  root   368 Nov 24 08:45 /etc/d_passwd

# /etc/d_passwd contains all 'initial programs' allowed 
# when invoked on a line specified in /etc/dialups
# /bin/sh:13characterEncryption:
# The encrypted password is drawn over via grep after applying
# /bin/passwd to a superfluous entry in /etc/passwd.

/bin/sh:JUNK: No login possible
/bin/ksh:skLrmQZO73Y4K: Password required on ksh login
/bin/rsh:: No password required on 'guest' rsh login

# A line to allow uucp entry with no password:
/usr/lib/uucp/uucico::

# Use links to different shell names to cause certain login ids 
# to require Dialup password, while other logins using the same
# shell with a different name don't need a password.
