My CDMA phone connects to the laptop via a USB cable. So I have to configurate the kernel with USB Modem support.
Device Drivers -->
USB support -->
[M] Support for Host-side USB
[M] USB Modem (CDC ACM) support
Check if the device is well reconized after install and modprobe the module(cdc_acm).
# dmesg | grep acm usbcore: registered new driver cdc_acm drivers/usb/class/cdc-acm.c: v0.23:USB Abstract Control Model driver for USB modems and ISDN adapters
Great, the device has been recognized. Then create the ttyACM0 node in /dev is it does exist.
mknod /dev/ttyACM0 c 166 0
Edit the configuration file /etc/conf.d/net.ppp0 (or .ppp1, .ppp2). Here’s mine
# Config file for /etc/init.d/net.ppp0
PEER="cdma" # Define peer (aka ISP)
DEBUG="yes" # Turn on debugging
PERSIST="no" # Redial after being dropped
ONDEMAND="no" # Only bring the interface up on demand?
MODEMPORT="/dev/ttyACM0" # TTY device modem is connected to
LINESPEED="230400" # Speed pppd should try to connect at
INITSTRING="" # Extra init string for the modem
DEFROUTE="yes" # Must pppd set the default route?
HARDFLOWCTL="yes" # Use hardware flow control?
ESCAPECHARS="yes" # Use escape caracters ?
PPPOPTIONS="" # Extra options for pppd
USERNAME="card" # The PAP/CHAP username
PASSWORD="card" # Your password/secret. Ugly I know, but i
# will work on something more secure later
# on. 700 permission on /etc/init.d/net.ppp0
# should be enouth for now.
NUMBER="#777" # The telephone number of your ISP
# leave blank for leased-line operation.
REMIP="" # The ip of the remote box if it should be set
NETMASK="" # Netmask
IPADDR="" # Our IP if we have a static one
MRU="768" # Sets the MRU
MTU="768" # Sets the MTU
RETRYTIMEOUT="60" # Retry timeout for when ONDEMAND="yes" or
# PERSIST="yes"
IDLETIMEOUT="600" # Idle timeout for when ONDEMAND="yes"
PEERDNS="yes" # Should pppd set the peer dns?
AUTOCFGFILES="no" # By default this scripts will generate
# /etc/ppp/chat-isp, /etc/ppp/chap-secrets,
# /etc/ppp/pap-secrets and /etc/ppp/peers/isp
# automatically. Set to "no" if you experience
# problems, or need specialized scripts. You
# will have to create these files by hand then.
AUTOCHATSCRIPT="no" # By default this script iwll generate
# /etc/ppp/chat-${PEER} automatically. Set to "no"
# if you experience problems, or need specialized
# scripts. You will have to create these files by
# hand then.
# Directory where the templates is stored
TEMPLATEDIR=/etc/ppp
Then have to manual edit two additional files /etc/ppp/chat-cdma and /etc/ppp/peers/cdma.
# /etc/ppp/chat-cdma: 'ABORT' 'BUSY' 'ABORT' 'ERROR' 'ABORT' 'NO ANSWER' 'ABORT' 'NO CARRIER' 'ABORT' 'NO DIALTONE' 'ABORT' 'Invalid Login' 'ABORT' 'Login incorrect' '' 'ATZ' 'OK' 'ATDT#777' 'CONNECT' '' 'TIMEOUT' '5' '~--' ''
# /etc/ppp/peers/cdma: connect "/usr/sbin/chat -v -f /etc/ppp/chat-cdma" defaultroute usepeerdns /dev/ttyACM0 230400 local novj
Now everything is OK. To dialup the Internet simply type
/etc/init.d/net.ppp0 start
The CDMA ISP is China Unicom.
