/etc/dialups contains a list of the pathnames of devices which are to
be considered "dialup" lines and for which an additional dialup password
will be required.  Use the full pathname: "/dev/tty29", one name per line.

/etc/d_passwd contains the encrypted passwords and the corresponding shells:

/bin/sh:vyEGlsxgLaDj.:
/usr/lib/uucp/uucico::


The dialup password is requested after (and only after) a username and
password has been validated.  Hence getting the propt for a Dialup Password
means the you have a good username and password.  The password is dependent
on the shell in the user's /etc/passwd entry (/bin/sh is the default if the
shell is not explicitly mentioned in /etc/d_passwd).  The null entry above
means that uucp connections don't get asked for a dialup password.
