[ale] AT&T connect via PPP

[Glynn Black]

I'm making a move from a local ISP here in Savannah to AT&T. Judging
from the PPP readme and the following information from bootup and
/proc/net/dev I believe I have my kernel configured right. 

from bootup: 
PPP: version 0.2.7 (4 channels) NEW_TTY_DRIVERS OPTIMIZE_FLAGS
TCP compression code copyright 1989 Regents of the University of
California
PPP line discipline registered.

from /proc/net/dev:

I pulled information off http://www.toppig.com/wurd/linux.html and
adopted the login script to my circumstances. For reasons unknown to
me, I can't seem to get my modem to dial out. My modem works, I can
dial out with minicom and manually dip/slip via my local isp, but I
keep getting "/dev/cua3 permission denied" when I attempt PPP.

toppig script:
#!/bin/sh
/usr/sbin/pppd name "blackgr at worldnet.att.net" -d connect \
        '/usr/sbin/chat -t 45 -v ABORT BUSY "" ATDT6516000 CONNECT ""' 
        /dev/cua3 57600 noipdefault modem defaultroute crtscts

from ppplog:

I used some chat parameters from the PPP Howto to try and reset my
modem (along with various different combinations), but same deal.

script:
#!/bin/sh
/usr/sbin/pppd name "blackgr at worldnet.att.net" -d connect \
        '/usr/sbin/chat TIMEOUT 3 "" \rAT 0k-+++\c-OK AT&D2&C1 TIMEOUT
60 OK ATDT6516000 CONNECT ""' 
        /dev/cua3 57600 noipdefault modem defaultroute crtscts

STDOUT:
sh: D2: command not found

sh: 60: command not found
/usr/local/bin/worldnet: /dev/cua3: Permission denied

Sep 25 22:38:08 sx pppd[123]: Exit.
Sep 25 22:38:08 sx chat[125]: Can't get terminal parameters: Invalid

I've gone through readmes, FAQs, howtos and books and I'm still
without a clue.  Anyone have any ideas what I'm doing wrong???

Thanks much,
