LinuxQuestions.org - configure lucent win modem at command line

i am trying to install lucent win modem from the command line in redhat 7.3. after installing the modem, kudzu recognized it and asked to configure it (which I did).

1. check to make sure modules hav loaded

[root@work root]# lsmod

2. copy scripts from the /usr/share/doc/ppp-2.04/scripts/ppp-o* /etc/ppp

3. edit the ppp-on script with
*************************************************
#!/bin/sh
#
# Script to initiate a ppp connection. This is the first part of the
# pair of scripts. This is not a secure pair of scripts as the codes
# are visible with the 'ps' command. However, it is simple.
#
# These are the parameters. Change as needed.
TELEPHONE=703-994-4005 # The telephone number for the connection
ACCOUNT=myname@speakeasy.net # The account name for logon
PASSWORD=mypassword # The password for this account (and 'Gracie Allen')
LOCAL_IP=0.0.0.0 # Local IP address if known. Dynamic = 0.0.0.0
REMOTE_IP=0.0.0.0 # Remote IP address if desired. Normally 0.0.0.0
NETMASK=255.255.255.0 # The proper netmask if needed
#
# Export them so that they will be available at 'ppp-on-dialer' time.
export TELEPHONE ACCOUNT PASSWORD
#
# This is the location of the script which dials the phone and logs
# in. Please use the absolute file name as the $PATH variable is not
# used on the connect option. (To do so on a 'root' account would be
# a security hole so don't ask.)
#
DIALER_SCRIPT=/etc/ppp/ppp-on-dialer
#
# Initiate the connection
#
# I put most of the common options on this command. Please, don't
# forget the 'lock' option or some programs such as mgetty will not
# work. The asyncmap and escape will permit the PPP link to work with
# a telnet or rlogin connection. You are welcome to make any changes
# as desired. Don't use the 'defaultroute' option if you currently
# have a default route to an ethernet gateway.
#
exec /usr/sbin/pppd debug lock modem crtscts /dev/ttyS0 57600 \

**************************************************

4. make the scripts executable
chmod +x /etc/ppp/ppp-o*

5. monitor modem for error messages:

6. initiate the dialup script

/etc/ppp/ppp-on

(see the above tail error messages. please note that i initially followed the script's suggestion to rename /dev/ttyS0 as dev/modem if kudzu recognized the modem and got an error message that /dev/modem "was not found." Therefore, I switched it back to ttySo. Now I get the error message:
ttyS0 is locked by pid 1053."
