Problem connect to my ISP

[mc100314 macau ctm net (Michael Chan)]

Hi,

I am setting up my ppp to connect to my ISP. However it failed and I got
this error message in /var/log/messages:

Feb  3 01:42:11 localhost pppd[282]: Serial connection established.

Here is the script of my ppp-on:

(snip...)
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 TELEPHONE ACCOUNT PASSWORD

DIALER_SCRIPT=/etc/ppp/ppp-on-dialer

exec /usr/sbin/pppd debug lock modem crtscts /dev/modem 115200 \
	asyncmap 20A0000 escape FF kdebug 0 $LOCAL_IP:$REMOTE_IP \
	noipdefault netmask $NETMASK defaultroute connect $DIALER_SCRIPT

I'm appreciated if any body can help me solve this problem out.
