I attempted to send a GSM 7 bit default alphabet message in text mode from HyperTerminal and a SMS-STATUS-REPORT is wanted by using the following AT commands:
AT+CMGF=1
OK
AT+CSDH=1
OK
AT+CNMI=2,1
OK
AT+CSMP=32,167
OK
AT+CMGS="+6590264987"
> This is the first line.
> Ｔhis is the last line. ^Z
+CMGS: 10 (1)
OK
+CDS: 2, 10, "+6590264987", 145, "05/10/12/14:20:11+08", "05/10/12/14:20:17+08",0 (2)
Surprisingly, neither of the supposed echo message (1) and (2) had never been displayed on my terminal. However, the short message could still be delivered to the destine handphone successfully. The model of the handphone connected to the serial port is Nokia 6670. Who can help to tackle the problem?
