Ubuntu8.04 deal with CDMA Internet access

In fact, I worked in Ubuntu8.04 mainly to use Erlang to develop new things that will be ready to run on the platform in the future. When I was idle, I tried to toss various configurations on the ubuntu system, before going to bed at night, I got a new harvest. After the local area network is connected to the printer in the afternoon, the CDMAPCMCIA card is successfully configured for dial-up access. The general situation is as follows. # Sudoapt-getinstallsetserialpcmciautils (two tools are installed) # sudop

In fact, working in Ubuntu 8.04 mainly aims to use Erlang to develop new things that will be ready to run on the platform in the future. When I am idle, I try to toss various configurations on the ubuntu system, before going to bed at night, I got a new harvest.

After the local area network is connected to the printer in the afternoon, the cdma pcmcia card is successfully configured for dial-up Internet access. The general situation is as follows.

# Sudo apt-get install setserial pcmciautils (two tools are installed)
# Sudo pccartctl info (subcommands such as status, eject, and ls can also be used. For details, refer to man)
# Dmesg | grep tty (get something similar to the following)
[34.574046] 0.0: ttyS0 at I/O 0x3f8 (irq = 3) is a 16C950/954
We can know that ttyS0 is a CDMA card device. Continue with the subsequent operations.

# Sudo vim/etc/wvdial. conf enter the following content
[Modem0]
Modem =/dev/ttyS0
Baud = 57600
SetVolume = 1
Dial Command = ATDT
Init1 = ATZ
FlowControl = Hardware (CRTSCTS)

[Dialer Defaults]
Phone = #777
Username = card
Password = card
Stupid Mode = 1
Inherits = Modem0

Continue subsequent operations
# Sudo vim/var/lib/setserial/autoserial. conf (enter the following content)
/Dev/ttyS0 uart 16950/954 port 0x03f8 irq 3 baud_base 230400 spd_normal skip_test

Or you can run the following command without making the above modification, but you only need to run it once before each dial-up.
# Sudo setserial/dev/ttyS0 baud_base 230400)

Now, the configuration is complete and you can dial up.
# Sudo wvdial

The output content similar to the following indicates that the operation was successful. Otherwise, try again.
--> WvDial: Internet dialer version 1.60
--> Initializing modem.
--> Sending: ATZ

Do not close the window. Otherwise, the window will be disconnected. If you want to disconnect the window, press CTRL + C and you will see the following output:

Caught signal 2: Attempting to exit gracefully...
--> Terminating on signal 15
--> Pppd: �� [06] [08] �� [06] [08] [18] �� [06] [08]

--> Disconnecting at Wed Aug 6 03:04:41 2008
After connecting to the Internet, you can use ifconfig-a to check the network connection. You should be able to see the ppp0 network device parameters.

Note:
If the network still fails after the dial-up is successful, it may be caused by a default route problem. You can run the following command to solve the problem:
# Netstat-rn (view the current route table or use the route command)
# Route add default ppp0 (add default route)

Now it should all be done. I hope you will be as lucky as me!

Note: My CDMA card is a PANDA brand, which is a very common domestic product. You can see the following information through the pccardctl info command:

# Pccardctl info
PRODID_1 = "PANDA"
PRODID_2 = "CDMA"
PRODID_3 = "CARD"
PRODID_4 = "D"
MANFID = 0279,950 B
FUNCID = 2
