Modem-To-Modem Communication... So Lost

Communication Modem To Modem Problems
I have a program that dials and connects with a machine running an answering program. The program dials, connects, sends 6's till it sees a 7, then sends 3 passwords, one at a time after receiving A's from the answering program. It then sends files. My problem is, I had it working on one machine(in VB, not compiled), but when I try it on 2 different machines, I connect, but never see any input or output on either machine. I have also been having trouble with certain modems not being able to connect to each other. I have a third party control that works just like the MSComm control with a few extras. I tried using both controls, the results were the same. I am just learning programming, and the person who wrote the original answer program, programs in DOS, so maybe we are just missing something that windows controls. One more thing, the machines that the program worked on were Win95 and a non windows machine(answering machine). The program won't work on a Win98 machine sending to a non windows machine. Here is a sample of the code that worked on the one Machine:

private Sub Command1_Click()
'
Open "c:TestCommlog.fil" for Output as #8
Open "Param.dbs" for Random as #2 len = 256
get #2, 1, PR
Pass$ = PR.PASSWORD

If Time2& - Time1& > 45 then
H% = 1

Modem To Modem Communication
is it possible to write a VB program that can control 32 modems, with a dialog box for each modem, to accept incoming calls? I know how to do it with one modem, but I haven't found anything on multiple modems. We have a program that does this which is written in C++ but I don't know much about C++, I am strong in VB, so I'd like to possibly rewrite it in VB so I will be able to better support the software.

Thanks!@

USB Modem Communication
Hi all

I'm facing problem in communicationg to an USB modem. Earlier i was using the COM port to connect to modem using the MSCOMM control of VB.

But now I want to shift to USB modem since I can connect multiple modems to one system and make a server program in VB which creates different instances of itself and listens to the USB port. So if any of my customers dial to the server, modem that is free and connected to the server should receive the request and as soon as the modem starts the program hsould start listening to the request.

Can any one help me on how to acheive this .. meaning listening to a USB port

Thanx in advance

Modem Communication In VB...
I have a server which is essentailly a voice mail server. That's not how it's sold, but that's what it is. Has a dialogic card (16 port) and rocketmodem (4 port).

The question (for now ) is this:

We've been looking for a way to automate some processes. The main hurdle is a means to dial into the system, enter a 7 digit DTMF user ID (let's use 4134134 as the touch tone example), then enter a 2, then a 9, and then another 9 and loop this process (the 2, 9, 9 part) as many times as the user has requested in a text box called NumberOfJobs.

Any ideas? I've played with MSCOMM and some thrid party OCX's with little to no success. With MSCOMM I can dial into the system which seems to work fine (shows up on the server's voice monitor), but it's inputing the DTMF tones for the corresponding user prompts that's not working.

I've searched through this and a bunch of other VB forums for answers and have tried all of the basic TAPI tuts. I'm stuck, please advise.

Any help would be greatly appreciated.

Modem Communication
Can any body help me to find out how can I do a file transfer between two computers by using a Modem (dial-up connection)?

As I noticed, there is a MSComm.Ocx in VB that can do the connection. My question is how can I make sure that the file contents that I output to the Modem are correctly or not.

Will the MSComm or the Modem do the error detection & correction for me?

Thanks for your help.

Req-HOWTO Add A Serial Modem To Modem Devices List
Hello.
I am trying to write an app that performs the functions of the windows "Add Modem" wizard. I am working with a wireless phone box DOWTEL CDMA 2000 with an RS-232 serial port

1: I am trying to add a modem device to the list of modems windows displays in the "Phones And Modems" control panel applet.
2: I am aware this can be done using the "Add Modem" wizard. I want to achieve this automatically, since Windows 95 to win XP and Server OSes support Standard Modem Types (Standard 33600 bps modem specifically)
3: I used an API Spy to monitor the API calls made to windows when a modem is being added. here is a list.

DeviceIoControl
GetModuleFileNameW
GetProcAddress
LoadLibraryA
LoadLibraryExW
LoadLibraryW
NtConnectPort
NtCreateFile
NtDeviceIoControlFile
NtFlushBuffersFile
NtFsControlFile
NtNotifyChangeDirectoryFile
NtOpenFile
NtQueryAttributesFile
NtQueryDirectoryFile
NtQueryInformationFile
NtQueryVolumeInformationFile
NtReadFile
NtRequestWaitReplyPort
NtSecureConnectPort
NtSetInformationFile
NtWriteFile

4: MSDN has a section on serial communications with API code in C++.. i do not know C and have at least 70 modems to configure before august. I need to automate this process. all the activex controls i have seen tell you how to work with modems already installed not how to install them with the API windows uses. they all claim to expose everything the windows code does, but there is no Addmodem function.. I guess that is what i need.

Thanks

Sending Data From Modem To Modem
Hello,

I have 2 modems which i am using to send data between 2 vp apps. At least that's what i want to do, but i'm not too sure how.

Here's what i think i need to do. I want my modem A to dial the modem B on my pc. Then i want the vb app on modem A to send data to the VB app on modem B . So i need the mscomm control to send AT commands to modem A so it can dial modem B .

Has anyone done this before ? Just need some tips as to how to get started. How do i actually send a string ( my data) using an AT commands, to the remote modem ?

Really need some help asap

Thanks.

Need Help With Modem
Since the ringer on my phone broke, I have been trying to make a program that listens for incoming calls and plays a wav file through my sound card, but I'm not having any luck. I have even looked at a lot of Caller ID source codes but they don't seem to work either. I wrote a program in Quick Basic for DOS and it worked fine, but I need something that is Windows based. Since VB doesn't support the OUT command, I'm lost.

Here is the source for QB:

count = 0
CLS
OUT &H3E8, 255
A = INP(&H3E8)
begin:
DO
IF count <> 0 THEN LOCATE 2, 55: COLOR 2: PRINT "Call Last detected at "; ltime$
IF count <> 0 THEN LOCATE 1, 1: PRINT "Press [c] to confirm detected call"
LOCATE 10, 30: COLOR 15: PRINT " Monitoring Phone Line "
LOCATE 23, 1: COLOR 7: PRINT "Press [ESC] to Exit"
x$ = INKEY$
IF x$ = CHR$(27) THEN END
IF UCASE$(x$) = "C" THEN
count = 0
LOCATE 1, 1: PRINT " "
LOCATE 2, 55: PRINT " "
END IF
LOOP WHILE INP(&H2E8) = A
here:
ltime$ = TIME$
count = count + 1
DO
OUT &H3E8, 255
COLOR 18, 0
LOCATE 10, 30: PRINT "Incomming Call Detected"
FOR b = 200 TO 3000 STEP 250
SOUND b, 70 / 100
NEXT b
FOR y = 1 TO 2
SLEEP 1
x$ = INKEY$
NEXT y
IF x$ = CHR$(27) THEN END
GOTO begin
LOOP UNTIL INP(&H3E8) = A
GOTO begin

Modem To Modem (not Using Web)
Hi,

I have a relative who does not have web access.

That is, I dial out on my modem to his home phone number, and connect to his computer via his modem.

hello sir,
I would like to know weather there is any site or do u know any API function for Telephony Aplication.Actually i want an API function which i can include in my project that will interact with modem .
To be very clear ,if some one dials then it comes on to my phone then from there it should be connected to modem and then to my software. Now my API or some code detects the phone number and then it gives him some options and then he will press the number of option which he wants.That is what i want to do.So please give me some code or some idea how to go on it .I want it in vb and vc++ .It will be preperable if i get it in VC++.
I will be waiting for your mail to come.
