I meet a problem using pppd, My CDMA module is WAVECOM Q2358C,and my dailing scripts as follows:
-----------------------------------------------------------------------------------------
#/etc/ppp/peers/cdma
# Most gprs phones don't reply to LCP echo's
lcp-echo-failure 0
lcp-echo-interval 0
# Keep pppd attached to the terminal:
# Comment this to get daemon mode pppd
nodetach
# Debug info from pppd:
# Comment this off, if you don't need more info
debug
#kdebug 7
# Show password in debug messages
show-password
# Connect script:
# scripts to initialize the GPRS modem and start the connection,
# wvdial command is for Orange SPV while other phones should work with #chat
connect /etc/ppp/peers/cdma-connect-chat
#connect "/usr/bin/wvdial --chat --config /etc/ppp/peers/cdma-wvdial.conf"
# Disconnect script:
# AT commands used to 'hangup' the GPRS connection.

# /dev/ttyS0 for serial port (COM1 in Windows),

# IP addresses:
# - accept peers idea of our local address and set address peer as 10.0.0.1
# (any address would do, since IPCP gives 0.0.0.0 to it)
# - if you use the 10. network at home or something and pppd rejects it,
# change the address to something else
#:10.0.0.0
# pppd must not propose any IP address to the peer!

# Add the ppp interface as default route to the IP routing table

# already present, when the GPRS connetion should be set as the default #route
# to the network
#replacedefaultroute

# ppp compression:
# ppp compression may be used between the phone and the pppd, but the
# serial connection is usually not the bottleneck in GPRS, so the
# compression is useless (and with some phones need to disabled before
# the LCP negotiations succeed).

It seems that after the pppd program passing througn LCP, the modem
can't receive any acknowledge from the ISP, which is China Unicom,
the login number is '#777', both the login name and password are 'CARD'.
There should be some mistakes bur I am unable to find it out.
Eagerly Waiting for a response!
Thanks!
