Actually in my earlier mail by mistake I wrote about 'broadband'. What I really want is internet connectivity from my Ubuntu Edgy 6.10 Laptop and my cellphone. Can you please help me on: which scheme I may use, and will that work smoothly on my laptop? I don't know anything about this kind of Internet connection. You have to suggest me about how to install and all other details too.

I use Bluetooth+GPRS on my laptop. The speed I get is 4.5 to 6 KBPS which is okay for downloading mails to your MUA but terrible if you are interested in doing heavy duty browsing. My phone model is Nokia 6670 and service provider is Airtel, you have to subscribe to their "Mobile Office" service for this to work. I had a lot of problems when configuring this setup. I had to google a lot and not surprisingly, Airtel's GPRS helpdesk was not at all helpful when the question of OS came up. The tech that I talked to knew only about the "Other" OS. Below is the relevant portion of /etc/bluetooth/rfcomm.conf .

rfcomm0 { bind yes; device 00:0E:ED:F8:61:0B; channel 1; comment "Veejay's 6670"; }

I use KPPP as the dialer. You will have to create a new modem in the KPPP configuration. The modem configuration in KPPP is as below.

Modem Name : <whatever> Modem Device : /dev/rfcomm0 Flow Control : Hardware [CRTSCTS] Line Termination: 115200

Enter the following in modem commands.

Initializing string 1 : ATZ Initializing string 2 : AT+CGDCONT=1,"IP","airtelgprs.com","",0,0

# I got the above value from the Airtel GPRS helpdesk. So it would be a good idea to talk to your service provider beforehand.

Init response : OK No dial tone detection : ATX3 Dial string : ATDT Connect response : CONNECT Busy response : BUSY No carrier response : NO CARRIER No dialtone response : NO DIALTONE Hangup string : +++ATH Hangup response : OK Answer string : ATA Ring response : RING Answer response : CONNECT DLP response : DIGITAL LINE DETECTED Escape string : +++ Escape response : OK

Next you need to create a new Account. Use the Manual configuration instead of the Wizard. Under the Dial tab, the entries are as follows.

Connection name : <whatever> Phone number : *99# Authentication : Script-based

The remaining setting can be left to the default values. There are two phone numbers that can be used here. I don't remember the other number, but you can get them from your service provider's GPRS helpdesk.

I have also used Tata Indicom's CDMA data card (Huawei EC321) on FC5. I was told that this is the most linux friendly data card, and the source was not exaggerating. The card was not mine but I got to test it for an hour or so. The connection speed was over 15KBPS. I had to use wvdial for dialing as the help I got was for it. I didn't have the card long enough to adapt the settings for KPPP. The contents of wvdial.conf is below. AFAIR, I didn't have to change it much, except maybe the device in [Modem0]. That value I got from the output of /var/log/messages when inserting the card.

[Modem0] Modem = /dev/ttyUSB0 Baud = 230400 SetVolume = 0 Dial Command = ATDT Init1 = ATZ Init3 = ATM0 FlowControl = CRTSCTS

[Dialer vdata] Username = internet Password = internet Phone = #777 Stupid Mode = 1 Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Inherits = Modem0

Hope this helps.
