Receive Incoming SMS Messages Via Gsm Modem In Program?
Jul 21, 2009
I am working on an assignment whereby i am requested to receive incoming messages via a gsm modem, i have tried to do so by writing at commands to the serial port where the gsm modem is connected to but there's one specific line which gives me error when i tried writing it to the serial port, (AT+CMGL= "ALL") which returns me an error: CMS ERROR: 305 which means Invalid Text mode parameter The following is the codes i have done up to so far, can anyone tell me what is the correct way to write this specific line to the serial port or is there any other methods that is able to do the same thing?[code]...

May i know how to insert a AT command method inside my program to receive incoming sms?
My program is in visual basic windows form 2005.
Here is how my program goes.
After i click connect button in my application, the gsm modem will automatically read the incoming sms and display in the textbox on the program.
I already have the list of AT commands to be used, they are :
1. AT
2.AT+CMGF=1
3.AT+CMGL="ALL"
I also would like to know how to declare these commands as string inside the program.
Here is my program so far:
CODE;
This code is for the user to click on connect button which will connect to the serial port. So after connecting the modem will then auto read and display new incoming sms.

I am having problem receiving data from serial port. Btw, I am new to Visual studio 2010 too.
I do a test program on my PIC so that when button1 press, it will send character "Y" to visual studio; when button2 press, it will send character "N" to visual studio. I know for VS 2010, sending data out is by the command

I am working on a program to poll SMSes automatically, i am using the serialPort_DataReceived event to detect any SMSes coming through the serialPort
Private Sub serialPort_DataReceived( _
ByVal sender As Object, _
ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) _
Handles serialPort.DataReceived
but the message i received does not contains the full information, may i know that if there is any other received data event that can be used to receive data coming through the serial port which can better receive data from a gsm modem?

I'm using the TcpClient and TcpListener classes to read/write to the network when a request comes in on port 25. All I'm trying to do at the moment is make it so that my server program can receive SMTP messages from other SMTP servers. I've tested in Telnet - if I connect to my own IP on port 25 and type EHLO, MAIL FROM, RCPT TO, DATA etc then all works as it should and the details I entered are logged by the program (it doesnt do anything about delivering these details/email yet).all looks good... but then when I try and just send an email to my domain from my work account I can see that a connection is made to my program and the string "EHLO workdomain.com " is received by my program - my program responds to the remote SMTP server with "250-mydomain.com Hello" and then a CrLF and then "250-OK". After that point however, my app does not receive anything further at all from the server at work. I'm guessing I am doing something wrong with the data I'm returning when it sends EHLO but can anyone point me in the correct direction?
I was using telnet to test with, it seems that I have made it work only with telnet.In telnet each time I type a key the data is passed to the server, however with a real SMTP server it just sends each entire command in one go. So after altering my server a little I can now get it to respond with the 250-OK which I thought it already was doing.. but it still doesnt work. The remote server just sends EHLO and then thats it nothing more.Something interesting, at the moment I am ending all of my responses to the remote server with VbLf - if I change this to VbCrLf (which is what I believe it is meant to be according to the SMTP standard) then I get an infinite amount of empty strings sent to my program (or perhaps some other character that just shows as an empty string in intellisense when stepping through the code). Changing it back to just vbLf or ControlChars.Lf makes it go back to just sending EHLO and then nothing else..

I want my application to be able to communicate 2-way between the application on another computer and the host server which will be running on my computer.I want to use the BackgroundWorker built into vb to create a thing to make it listen for incoming messages, and also send out messages to the client.The client needs to listen and receive, same as the server, because both need to communicate with one another.I do not know how I can make it do either sending nor receiving.I would be using two different background workers to keep the code seperated and organized so that I will understand what code is for what.
I want the code to say that if i receive the message "Apple" without the "" and cap sensitive, then it will change Label1.Text = "That worked, word received Apple" or something similar to that. ( This is because I am ignorant and I want it to interpret the text sent through to figure out what the application is supposed to do, and last time I couldn't figure out how to make it do something when a certain text was received.

I want to write a Solution with VB.Net for Receive "Users" requests and Send specified information to
them with SMS.I use D-Link GSM-Modem (Model:DWM-156).
This model/type of GSM-Modem, has embeded Driver and a Application for Sending/Receiving SMS.on it, and also we can attach MicroSD to the Device. 1-Send/Receive with GSM-Modem and D-Link's application :
when i attach GSM-Modem to USB port, D-Link' app , run automatically , then I heared noises on my Speaker, like when turn on a Mobile. I think this Signals "Hand Shake" with My GSM-Network.

I am wondering is there any code to get the text reply from the modem? I am using the itegno W3800 modem. I have used the below method so far but apparently VB.NET windows form doesnt see the incoming data. The message box comes out empty. But when i try the same method with the TMAS Siemens GSM modem, VB.NET can see the incoming data and display out the data string.
here is the code that i have written:
serialPort.Write("AT" & vbCrLf) 'set command message format to text mode(1)
receiveddata = serialPort.ReadExisting()
it works for the TMAS gsm modem.
The baud rate for the TMAS GSM modem is 9600 and the baud rate for the itegno modem is 115200.
For the itegno modem, the data is sort of like stuck at the serial port as after every time i pressed on the button for example "AT"
this "AT" command gets "stuck" at the serialport and run only when i have connected through the serial port in hyper terminal.
I am thinking is it the baud rate for 115200 is too fast for VB to handle? And also is there any way to solve this problem?
i have to revert back to the itegno modem for use for my project at the end of the day.

I am using sockets to send message between computers. I send the messages alright. What I want is when the message "x0x" comes, the client must be closed within 5 minutes. Teh admin can cancel the request by sending message "-xx" as well. The routine that checks for incoming connections and accepts messages uses WHILE TRUE...END WHILE since it must always listen. Once I get a message, I need to fire a timer control or other that fires within 5 minutes. But the program cant leave the WHILE TRUE at all. If i exit it early, the timer fires and the program does get exit. How do I fire the timer or other routine while still the WHILE TRUE routine checks for incomin connections and messages?

I've looked around at pretty much all the SMS posts here on SO and the best answer I've come up with so far is ZeepMobile. The only problem is, they're "in beta" and aren't readily accepting users. Is there a workaround for this, maybe receiving an email via text (kind of like how TwitPic does it?) somehow and parsing it?

I am attempting to call a remote modem using a local modem connected via USB. Programming language is VB.NET and I am using the SerialPort control to talk to the modem.
Communication is as follows:
I send: ATZ0[CR]
Modem responds: ATZ0[CR][CR][LF]OK[CR][LF]
I then try to dial a number:
I send: ATDTnnnnnnnnnn[CR] where nnnnnnnnnn is a valid number
The modem responds with:ATDTnnnnnnnnnn[CR][CR][LF]ERROR[CR][LF]
All other commands seem to work without any issues
For info the modem is a MultiTech MT5634ZBA-USB-V92
If I use hyperterminal and type the same commands in it works as expected and dials the number, so it must be something I am doing in my code, possible some setup in the SerialPort control

(from scratch as I've not done this before) how I can stream live through modem-to-modem connection. The modem here refers to dial-up modem (PSTN modem), there is no internet/lan involved.It will be 2 programs, the first is to transmit real-time video from webcam, and the second is to remote video from the first.
