How-TO: Connet CF GPRS/GSM (AudioVox RTM8000) to internet Options

[tamarian]

(Updated with less steps)

Hi folks,

I finally managed to get my Audiovox RTM8000 GPRS/GSM CF card to connect to the internet. I do have a Wi-Fi card, but I need to connect sometime when I'm not at a hot-spot, so this is an ideal solution for my needs.

My setup:

Sharp Zaurus SL-C760
Using Sash ROM (but a default ROM should work, as the Sash ROM gave me the same errors as the Sharp ROM, the bad Vcc error)
Audiovox RTM8000 GPRS/GSM compact flash card

GPRS/GSM provider: Fido www.fido.ca in Canada
Plan: data only, no voice. CDN$50, unlimited data

Fido network settings: (Note these, so you can replace with your own provider settings
APN: internet.fido.ca
User name: fido
Password: fido
DNS: none
IP: none

Fido simply asks for your smart card number, and the MEI number (from the bottom of your modem), and sets you up (activate)


Steps:

Note: You can download a gzip file containing serial_cs.o and sample scripys from here:

http://www.zaurususergroup.com/modules.php...q=getit&lid=183

Steps 1 and 2 are not required if you are using the Cacko Qtopia 1.2 ROM, as it contains the proper serial_cs module http://www.zaurususergroup.com/index.php?n...iewtopic&t=2232

Step 1.Download serial_cs.o driver. One place that has it available for download:

http://www.iral.com:88/~albertr/zaurus/mis.../serial_cs.o.gz

Step 2 Copy the serial_cs.o to the modules directory:

/lib/modules/2.4.18-rmk7-pxa3-embedix

Type

depmod -a
modprobe serial_cs

Step 3 edit the file /etc/pcmcia/serial.opts and set:

SERIAL_OPTS="uart 16550A"

Step 4 Insert the Audiovox RTM8000 card

Step 5A. Use the network setup application to create a dial-up PPP connection . Simply launch the network setup, select Dial-up PPP from the frop down menu. Click Add, Select, and enter the following information (Images of the screen attached below):

In the Account tab, enter any name, and in the user name and password fields, enter the username and password provided by your GPRS provider. In the phone number field, enter *99#

In the Modem tab screen (image provided below), enter the following modem init string:

AT+CGDCONT=1,\"IP\",\"internet.fido.ca\"

Simply replace "internet.fido.ca" with the APN for your GPRS provider.

Click "OK", and thin click "Connect".


That's it, you're done! The following steps are only required for debug, if the above didn't work


Step 5B Go to the directory /etc/ppp/peers

Create 3 files as follows

a. gprs (replace "fido" with your username)

CODE

# the two lines below help debugging, delete when things work fine

debug debug debug

show-password

# end debug

/dev/ttyS3

115200

crtscts

connect /etc/ppp/peers/connectgprs

user fido

usepeerdns

nomagic

mru 1500

mru 1500

:10.0.0.1

noipdefault

ipcp-accept-local

defaultroute

novj

novjccomp

disconnect /etc/ppp/peers/disconnectgprs

defaultroute

And second file, connectgprs (replace "internet.fido.ca with your provider's APN) Note, make sure you use tabs in editing this file, if you need a template use an original file from the links at the bottom, or wget http://kotinetti.suomi.net/mcfrisk/gprs-connect-chat and make the appropriate edits from this code:

CODE

exec /usr/sbin/chat -sVS

       TIMEOUT         5                              

       ECHO            ON                              



       ABORT           'nBUSYr'                      

       ABORT           'nERRORr'                    

       ABORT           'nNO ANSWERr'                

       ABORT           'nNO CARRIERr'                

       ABORT           'nNO DIALTONEr'              

       ABORT           'nRINGINGrnrnRINGINGr'    

       ''              rAT                            

       TIMEOUT         12                              

       SAY             "Press CTRL-C to close the connection at any stage!"

noipdefault

       SAY             "ndefining PDP context...n"  

       OK              ATH                            



       OK              ATE0V1                            

       OK              'AT+CGDCONT=1,"IP","internet.fido.ca","",0,0'  

       OK              ATD*99#                        

       TIMEOUT         22                              

       SAY             "nwaiting for connect...n"    

       CONNECT         ""                              

       SAY             "nConnected."

       SAY             "nIf the following ppp negotiations fail,n"  

       SAY             "try restarting the phone.n"

And last file, disconnectgprs

CODE

exec /usr/sbin/chat -s -V -S

"" "K"

"" "+++ATH"

Step 6 go to the directory /etc/ppp

edit the file chap-secrets

Add a line to insert your username and password, in my case fido and fido:

fido [tab] * [tab] "fido"

Step 7 Make sure your card is ready, type:

cardctl status

if it shows "suspended", then (only if it is suspended, otherwise skip this step) type:

cardctl resume

Step 8 Now the good part To connect, go to /etc/ppp/peers and type:

pppd calll gprs

That should do it!

Step 9 If you want to have the connect/disconnect through the GUI network setting application, simply create a modem connection with username/password and phone number as *99#, then click o.k. (tip: you can enter an accelerator proxy here, if your provider offers one).

Then copy the gprs script to override the generated Zaurus script.

cd /etc/ppp/peers
cp grps DIALUP*

Where DIALUP1234 (or any number) is the one created by the zaurus network app.

Note: Do not edit the connection from the Network setup menu, it will overwrite your connection script

Finally, this is a really quick how-to, as I've just connected right now, and thought I'd list all the info before I forget.

Try it out, and hopefully it will work for you too. If not, post here, and we'll try to sort out the problem.

Resources: I found the following info below helpful. I had to make adjustments, and after several trials and errors (4 days) it finally worked. I will list the links, just in case they help you, if my info doesn't work in your case:

Tips from members (copied from the devboard which has been shutdown)

1. Using voice GSM.

BTW: If you ever like to use you card as a phone try this:

ate1
OK
at+cpin="1111"
OK
atd 001 212 123 4567;
OK
ath
OK

The pin needs to be the pin of your sim card (PIN1). The semikolon after the telephone nunber is important. Otherwise you will try to make a data call.

Hi All,

I use the AudioVox RTM-8000D GPRS card on an Zaurus SL-5600 running OpenZaurus 3.5.3 with no problems. Getting it going was tricky. I've written a step by step howto covering the details. It's available here:

http://www.glugers.org/content.php?article.2

I'm now trying to get the RTM-8000D working on Fedora Core 4 with no success so far. It's plugged into my laptop via a CF-to-PCMCIA card. My dmesg output is simply:

cs: memory probe 0xa0000000-0xa0ffffff: excluding 0xa0000000-0xa00fffff
0.0: RequestIO: No more items

Any help would be appreciated.

Cheers,
George

It sounds like you need to add an identifier to the system so that it realises that this type of card is, basically, a serial device.

what does "cardctl status" and "cardctl info" tell you?

Cheers for the reply. Below are the outputs. I've also included the entries in /var/log/messages when I insert the card:
