Hi Ed,<br>Woop, I have the same results with +CBST. But still can not make data call although AT+CEER show "no error" ?<br><br>Btw, your data call is to a land-line modem ? My target is a data call between 2 FreeRunners or from FR to other mobile, I heard some where mobile-2-mobile data call is quite diffirent than to land-line modem. Is it correct?<br>
<br>PPP is only need after modem completes hand-shaking with far end modem. Unfortunately, I still can not have hand-shaking done :-((<br><br>Cordially,<br>Tuan<br><div class="gmail_quote">On Sun, Mar 22, 2009 at 8:10 PM, Ed Kapitein <span dir="ltr"><<a href="mailto:ed@kapitein.org">ed@kapitein.org</a>></span> wrote:<br>

<br>
well, it seems like you are almost there.<br>
you can check if the gsm network has data capabilities with the<br>
following command:<br>
<br>
atz<br>
OK<br>
AT+CBST=?<br>
<br>
+CBST: (0-7,12,14,65,66,68,70,71,75),(0),(0-3)<br>
<br>
OK<br>
<br>
i am able to make a call after that with:<br>
<div class="im">AT+CBST=7,0,1<br>
AT+CR=1<br>
</div>ATD xxxxxxxxxx<br>
<br>
the username/password i need is indeed my username/password for my<br>
dial-up ISP, but it is only needed *after* a successful call to my ISP.<br>
after a successful login i should be able to start a ppp link with my ISP.<br>
<br>
If i make a datacall to my home phone, i can hear the FR trying to<br>
initiated a data connection, kind of like a calling fax machine.<br>
So you could test that.<br>
<br>
A good source of information on ppp could be<br>
<a href="http://tldp.org/HOWTO/PPP-HOWTO/" target="_blank">http://tldp.org/HOWTO/PPP-HOWTO/</a><br>
I use no PIN, but i don't think that matters much.<br>
<br>
Good luck, i will try to make a full internet connection once i have my<br>
username password and let you know the results.<br>
<br>
Kind regards,<br>
