HI, how can i read out the message from the GSM modem. The follow code only manage to show "at+cmgl=all" which is not the mesage i want. anyone know how to solve it ?

vb.net Code:

[CODE]
With serialport
            .PortName = "COM6"
            .BaudRate = "115200"
            .StopBits = IO.Ports.StopBits.One
            .DataBits = 8
            .Parity = IO.Ports.Parity.None
            .ReadBufferSize = 10000
            .ReadTimeout = 1000
            .WriteBufferSize = 10000
            .WriteTimeout = 10000
            .RtsEnable = True
 
            .Open()
            .DiscardOutBuffer()
            'for reading sms
 
            atcCommand = "AT+CMGL=all"        'to read from inbox
            .Write(atcCommand + vbCrLf)    'execute command on buffer
 
'code manage to get out what it wrote in the atcCommand
            TextBox1.Text = .ReadExisting
 
        End With
[/CODE]

Hi,
there should be an 'incoming' event on the serial port that should list what comes back.

I know when I did this, I used the serial control from www.franson.com - although I know Dick Grier has some examples on his site

well.. i look through it. but there is no key word for incoming event.. is it possible send me a working copy..?? thanks

Hi,
take a look at the excellent article here - that should put you on the right lines.

My GSM modem don't have auto trigger function. it will not auto detect incoming data/msg.
How can i make my GSM modem auto detect incoming msg/data.

at+cnmi?
2,1,0,0
ok

but when i send a msg to my modem. it is not responing.. how am i going to make it auto detect ?

how do you know it isn't responding and it isn't your code.

Try downloading an evaluation of the terminal emulator from http://www.cam.com/vxhpc.html and trying your commands on that

coz i using the same code to phone is workable.. when i use the at+cnmi? command
it will auto trigger to read message from inbox.. my phone show a respone when it receive new message.. but my gsm modem is not responing..

Is it the same??
At+cmgl=all
or should it to be
at+cmgl="all"
