I have created a program using FaxServer and FaxDocument. I want to know if there is a way to determine programically if the modem is busy? Busy in terms of it could be sending/receiving a fax or another program is using it. I just need to know if its in use.

I am trying to determine if a modem is busy. I have tried using serial ports which from what i can see just tells me that something is tied to a port or not. It does not tell me if the modem is busy.
My overall question is How do can I determine if a modem is busy? For an added bonus, also is there a way to tell what device is using a particullar port?
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.

View 1 RepliesI 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
Details : I have the MultiModem (MT5656ZDX) . I wrote visual basic application for making the call using 'MakeCallAsynch(txtPhoneNumber.Text)' function. Also i have the callback event handler for get the line status and write the log. But my tapi call is not going the status except DAILING,PROCEDING,CONNECTED,DISCONNECTED and IDLE. Its not showing the line busy, phone swithed off status. Please guide me regarding this.

(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 5 RepliesI am using the following code to enumerate through com ports to determine if the attached modems are in use.When I get to my usb modem, it returns the correct "PostIsAvailable" status, but then it kind of locks up the modem and I get the following error when I try to manually query the modem I get: "The modem failed to respond. Make sure it is properly connected and turned on. If it is an internal modem, or is connected, verify that the interupt for the port is properly set."I either have to manually requery the modem or unplug/plug it again.This code works fine on my external serial modem, but not the USB modem.

I have a client program I wrote that waits for TCP communications. I found that when it was waiting, the form became unusable. I did some reading and learned about threading. Now it works great. Now I came to the point where I need to stop the program.. this is basically what I have:
[code]...
I figured I'd use the quit option to set the bool to false that the thread will see then do the proper closeout. However, it doesn't seem to work. After banging my head against the code, hehe, I realized that the thread is hung waiting for a client on the "AcceptTcpClient()" line.. so it's never getting a chance to evaluate SystemRunning.Is that an accurate assumption of the problem? If so, how does one deal with it?Also, I surmised that I probably should put my "end" statement at the end of the thread to be closed rather than my quit sub. I was afraid the marker boolean for the thread would get set and then the quit sub would immediately trigger "end" before the thread had a chance to close out. Is that also correct, or doesn't it matter?
How can I access data that WebBroswer1.navigate function is downloading from a website, while it is downloading it? If I access it once it has finished downloading it through the WebBrowser1_DocumentCompleted function, it only slows down my program, since it has to wait for the website to finish downloading to the control before I can access it.

View 1 RepliesI have a form with several buttons on it and when the user presses one of the buttons it begins a lengthy process (takes up to several seconds). What I want to happen is that any subsequent button presses that occur on any other button on the form are ignored until the process is complete from the initial button press. What actually happens is that subsequent button presses go into a queue and are executed in sequence as the processes for each complete. What I mean is, if each button executes a function that takes 2 seconds and I hit 5 buttons very quickly (in less than 2 seconds say) it leads to a sequence of events that takes 10 seconds.... what I want to happen is for it to lead to only the FIRST button press occurring and taking the 2 seconds that it's activated function takes.
I am writing software that interfaces with hardware through a USB to UART converter and am using virtual COM ports and timing is critical. I want something to occur ONLY when I press a button, not seconds later after being queued up and waiting for a previous operation to finish.

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.
