pppd: connect script failed

[ehung]

Hi everyone
I want to make a connection to internet with modem througth pppd
function.
But I got the error when I made a connection.
The error log is "pppd: connect script failed".
The below is my pppd and chat script file.

/** ppp-on ***
MYNAME=username
echo "PPP is using account ${MYNAME} to connect to ISP ${ISP} ..."
DIALER_SCRIPT=/data/HSDPA/pppondialer
exec /system/bin/pppd -detach modem crtscts \
/dev/modem 460800 noipdefault defaultroute \
noauth name ${MYNAME} connect $DIALER_SCRIPT

/**** pppondialer *****
exec /system/usr/bin/chat -v \
ABORT '\nNO DIALTONE\r' \
ABORT '\nBUSY\r' \
ABORT '\nNO CARRIER\r' \
ABORT '\nNO ANSWER\r' \
'' 'ATZ' \
OK ATDT*99***1# \
CONNECT ''

Could someone give me some suggestion?
Thank in advance

try ro run your chat line alone against /dev/modem
anyway I wonder why you put double quote around ATZ...CONNEC.
You also forgot to setup AT+CGDCONT=1,"IP","yourapn" before dialing

Hi François
Thanks for your reply.
I have remove double quote around ATZ...CONNEC and tried to run my
chat line alone.
But I got nothing form logcat and the chat process is still existence
until I kill that process.
If I just execute pppd /dev/modem, I got different log message.
========== logcat message ============
pppd : using channel 1
pppd : using interface ppp0
pppd : Connect : ppp0 <--> /dev/modem
pppd : LCP: timeout sending Config-Requests
pppd : Connection terminated
pppd : using channel 2
pppd : using interface ppp0
pppd : Connect : ppp0 <--> /dev/modem
pppd : tcflush failed: m
=======================================
Sorry to trouble you.
Could you give me some advice?
thank you.

Ok now you get connected but since you dial without defining AT+CGDCONT as I explained in my previous mail, pppd has nobody to talk to. you must define the apn prior to dialing in your chat script. Then pppd should be able to talk to a ppp server on the other side. add debug option to your pppd config to get more info about what is happening. There is a mistake in the pppd android code. It doesn't display correctly he franes in debug. It is pretty easy to fix.

Hi François
I have modified the script file as below but I got the same result.
pppd: connect script failed

/** ppp-on ***
MYNAME=username
echo "PPP is using account ${MYNAME} to connect to ISP ${ISP} ..."
DIALER_SCRIPT=/data/HSDPA/pppondialer

exec /system/bin/pppd -detach modem crtscts debug \

/dev/modem 460800 noipdefault defaultroute \
noauth name ${MYNAME} connect $DIALER_SCRIPT

/**** pppondialer *****
exec /system/usr/bin/chat -v \
ABORT '\nNO DIALTONE\r' \
ABORT '\nBUSY\r' \
ABORT '\nNO CARRIER\r' \
ABORT '\nNO ANSWER\r' \
'ATZ' \

AT+CGDCONT=1 "IP" "Fetnet01" \
OK ATDT*99***1# \
CONNECT

Another way, If I test it on the fedora linux os, I can get the chat
log message.
When I change the chat command from fedora system to the another chat
command that made by busybox,
I can't get chat log message anymore.

How do you think?
Thanks in advance again.

I think it should be

exec /system/usr/bin/chat -v \
ABORT '\nNO DIALTONE\r' \
ABORT '\nBUSY\r' \
ABORT '\nNO CARRIER\r' \
ABORT '\nNO ANSWER\r' \
'' 'ATZ' \

OK 'AT+CGDCONT=1,"IP","Fetnet01"' \
OK ATDT*99***1# \
CONNECT

Hi François
I have modified the script file, but the log message shows the same
error.
pppd: connect script failed
Does the chat command has something worong when I made it by busybox?
I feel that chat command doesn't work but I am not sure.
Thanks for your help!
