Hi, I need to use a T29s to send SMS passed from a microcontroller for a project. I have a data cable, but cannot find out what string I need to send to the phone to make it send an SMS. Ericsson claim that the T29 can't be used as a modem, and that the AT command set can't be used. Can anyone confirm this or has anyone done this kind of thing? Thanks, Ilya. |

It's sounds very strange!?!?
I don't known if T29s can sends SMS via AT Commands...
but i can give u the command so u can try 
open COM port which use by data cable and type:
AT+CMGS=length
pductrl-z/ESC
It returns mr 
where:
length: Integer; with AT+CMGF='0', this value indicates the length of the actual TP data unit (in octet units).
pdu: In case of SMS: GSM 04.11 SC address followed by GSM 03.40 TPDU in hexadecimal format. ME/TA converts each octet of TP data unit into two IRA-character long hexadecimal numbers.
In case of CBS: GSM TPDU in hexadecimal format.
mr: Integer; GSM 03.40 TP-Message-Reference.
