> T610 callback problem
Bookmark topic
I have a problem with dial-up modem connection trough HSCSD. I 'd like to use callback functionality to connect to my office. I can make succesful dial-up connection from my home PC (Infraport used to connect my PC and phone) to Office dial-up server. The problem occurs when the I configure Office-dial-up-server for callback functionality (it means: first I connect to server and set the number for callback and then server try to make data connection to my phone(PC)). I can make connection to dial-up server and type phone number for callback. Then the call is dropped and dial-up server starts to make callback. If I have set in the phone the next incomming call ("Calls-> Next call-> next incoming call-> ") "voice", after a while I can see incoming call from dial-up server, I answer it, but I don't get any login prompt from server and after a while connection is dropped. When I set the next incoming call "data", I don't receive any signalization of incoming call from server. I have tried to make this under Windows XP/Win2000(hyperterminal sw used) and Linux(RedHat9.0) on my PC. Under Linux I have used "minicom" software.
As modem initialization string I have used "ATZ" command, for dialling I have used "ATDdial-up_server_number" command and for answer of incoming call, I have used "ATA" command. I have tried make the same with other phones like Siemens-S55, Nokia-7250 and it works fine.
In next step, I have tried to use various modems on server side. I tried to make connection from server to home PC manualy- it means I tried to make data call(using AT commands) from server modem to my phone(T610) but with the same result. It looks like the T610 is not able handle incoming call properly.
Maybe I need to use some other type of modem initialization string for T610 or to use another type of connection between my home-pc and T 610 phone (bluetooth or USB cable).
Could any one tell me where I can find AT command list for T610 modem ???
Thank you in advance.

@vlado:
I have a list for the AT commands for T68i, and I believe they're mostly the same. Give me an email and I'll send it to you (about 1MB when zipped pdf file).
Interesting thing I noticed: I don't find these options in my T610:
in the "Next Call" menu I only have "Call and show ID" and "Call and hide ID"... nothing about VOICE/FAX/DATA... I have my data-number activated for about 2 years now.
I also tried to call my DATA number and answer it from HyperTerminal, but after the "ATA" command the phone answered in VOICE mode - there was no carrier signal.
I guess I'm doing something wrong.

edit:
AT+CNUM shows your registered Voice/Data/Fax numbers
AT+CBST? shows speed, name,
AT+CRC=1 enables extended result codes
I always get RING/VOICE but never RING/ASYNC for incoming data call and I don't know how to make my phone answer the call with CARRIER signal ;-(

Hi,
thanks for the offer, but I'v already found the T68i AT commands on the Sony Ericsson developer page and I'll make some tests with different settings of T610 modem....
I 'v post this problem to SE official support page too, so maybe they'll resolve this problem...

Here are the commands one may need to make the T610 Modem start acting like a standard PC modem...
AT
AT &F
AT V1E1S0=0&D2&C1
AT +CMEE=1
ATS7=60;+DS=3,0,2048,32;+IFC=2,2;
AT+DR=1
AT+CBST=0,0,1;+CHSN=1,1,0,4
AT+CR=1
AT+CRC=1
( Execute all these one after another and after the last one you can simply type: ATD0123456 and get connected
)
Explanation:
AT
(clear buffer)
AT &F
(Factory defaults)
AT V1E1S0=0&D2&C1
(V1-verbose output, E1-echo, S0-rings before answering, &C1 and &D2 - flow control - may be ommited)
AT +CMEE=1
(Provides extended error-reporting format)
ATS7=60;+DS=3,0,2048,32;+IFC=2,2;
(S7=60 - Timeout after dialing process is initiated and no connection is made - in seconds;
+DS - bidir V42bis compression
+IFC - sets RTS/CTS flow control over DCE)
AT+DR=1
(Provides extended report for +DS connection status)
AT+CBST=0,0,1;+CHSN=1,1,0,4
(+CBST - Autonegotiate Non-transparent ASYNC connection; +CHSN: configures HSCSD Non-transparent call configuration)
AT+CR=1
(Extended Handshake result codes: +CR: REL ASYNC)
AT+CRC=1
(Extended Incoming call information: +CRING VOICE/DATA)
-----------------
I managed to call and connect to regular Internet providers but still I don't know how to set the phone to answer in DATA mode. I tried to call from a GSM with DATA subscription and then my T610 recognized it as a DATA CALL, but in any other case I have no success
Will let you know in any progress I may (not
) have!

you need a different number for incoming data calls, and you change the "next call" to data in the menu.
