% uname -srm
NetBSD 1.1B i386
% sed -n 177,181p /usr/src/usr.sbin/pppd/main.c
    if (!options_from_file(_PATH_SYSOPTIONS, REQ_SYSOPTIONS, 0) ||
	!options_for_tty() ||
	!options_from_user() ||
	!parse_args(argc-1, argv+1))
	exit(1);
% 

1. /etc/ppp/options
2. /etc/ppp/options.ttyp1
3. ~/.ppprc
4. command line -- "/dev/ttym1 38400"

Perhaps you want:
-------------------------------------------------------------------
    if (!options_from_file(_PATH_SYSOPTIONS, REQ_SYSOPTIONS, 0) ||
	!options_from_user() ||
	!parse_args(argc-1, argv+1) ||
	!options_for_tty())
	exit(1);
-------------------------------------------------------------------

Good or bad, right or wrong, I'm not sure.
