My app is to send text messages to mobile phones using Hayes commands.Only 1 workstation has a Modem attached, but the app is a standalone on multiple workstations.
Is there a way to share this modem using virtual comports on the lan?
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.

View 1 RepliesI'm a novice and after toying with some basic ideas on how to talk to a modem with VB.net, I think there may be much more to it than I realize. (?) I know my modem is fine, I can use hyperterminal to call out on it with no problem.So, how involved is it to talk to a modem? My initial thinking was that I could simply talk to it via a serial port using AT commands sent and rcvd as a string.(?)My modem is set up with COM2 9600 8n1.I've setup a serial port with the same parameters in my code.
View 13 RepliesI am using a 3rd party communication component and it is able to tell me the names of installed modems. Given the modem name, I need the com port associated with that modem (so that I can set the modem baud rate directly through the serial port). I also need a way to determine if that port is already in use.

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?

Our project requires machine A to communicate to machine B using modem. For example, machine A will call machine B, issue commands and machine B sends the results back. Also we want machine B to transfer files to machine A if there is something to send.
View 14 RepliesI'm creating a small program in Visual Basic, using Visual Studio 2010, which communicates with a GSM modem via serial port.The connection works, I can even communicate properly with the modem and I can also send sms and mms .. But I can not handle the modem answers ... I'll explain:If I send a command like AT + CSQ modem replies with + CSQ 22.0. This command gives me the value of the signal as a response on a scale of 0-30 ... I can see on the screen (in a dedicated console) but I would like to manage the response in the sense that I would do something like that
IF (answer.text = "+CSQ 22,0") Then
label1.text = "Good"
ELSE
label1.text = "Bad"
END IF

I am doing a sms project using VB .net to connect to my gsm modem via serialport. All the connection and everything was working great and I can send and receive sms. Then here come a problem, I need to send long sms more than 160 chars. I read and did some research and I know that I need to use the pdu and udh. I managed to understand slightly of the pdu packet but is still quite confuse on that part.
Anyone can briefly explain the exact way to do the concatented sms (long sms)?Another problem is how can I use vb to encode the data into pdu gsm 7bit data? Is there any built in functions or do i need to write them myself?

I wrote a fax program that is using Microsoft FaxServer and FaxDocument on a windows 7 machine. I want to be able to check if the modem that the FaxServer is using is busy. I maybe busy for whatever reason (in use by another program, receiving or sending faxes, whatever). What currently happens, is if the modem is busy, the fax is sent to the Windows Queue and waits for the modem to get done. I don't want that to happen. So before sending I want to check if the modem is in use. I have a couple of things I have already done. But I am having issue tying them together.
I can get a list of ports for the computer and I can get the faxserver devices. But I would like to be able to do something like... take the faxserver device it is using(Com1, Com2, Com3...Whatever) and I want to check if it is free.
