I want to write a programme for modem but don't have any idea how to do. any body who can give guidlines

I am having a problem for setting the buffer size and data from the buffer in Voice recieve mode, I am making an answer machine and I need an advice about that. I am using visual basic but if there is any advice just in AT Commands that will be great

i try to access the modem with pascal
so many errors i encounter especially in
recieving the echos of the modem like "OK"
"CONNECT" "BUSY" and the dtmf tone response
please if its okey
give me some help

Anyone can give me a voice modem program sample to me. Please using AT-voice command to do it!
Thanks A lot!

I need to send a short message (voice) by a modem with Visual Basic.
Howt can I do that?
Thanks

I am struggling with the same voice problem as the rest of you, but I can answer some of your questions.
the at commands needed to dial a phone number are:
at #cls=
0 - data mode (for dialing an ISP)
8 - voice mode (for voice calls)at d9,123-4567
dials the number,
it returns ERROR if something goes wrong
otherwise it returns
VCON in voice mode, and
CONNECT in data modeon a modem using a rockwell chip the commands at +vrx and at +vtx receive and send voice respectively, but I can't seem to send voice correctly (receive seems to work)
recieving dtmf codes is easy, once you have made a voice connection (and you are not in voice receive mode) any DTMF tones read will result in the modem sending the message
0x10 [ascii for the number or symbol pressed]I still can't get the sending of voice to work, does anyone out there know how to do it?
Thanks

Hi All. Anyone know how to use TAPI with a voice modem to implement a meeting between 3 users. User 1 is calling from the PSTN, user 2 and 3 are LAN users running MS NetMeeting?
Any help please!

The explanation of AT voice commands can be found at this site : www.geocities.com/SiliconValley/Pines/5004/voice-cmds.html

Hi,
I need some basics regarding client/server (C/S) programming through a modem. Is it different from C/S programming through LAN? How can I tell my program to answer the modem when it is called, and how to pass/receive data through a modem. Do I need to use modem API's?
I really need help. Thank you very much.

Here's a excellent site for details on
MODEM programming strings...
http://www.modems.com/glossary/extend1e.htmlThis simple C++ program below run under DOS on my COMPAQ Presario 1200 (Windows 98) Visual C++
//=============================================
// Dialer.cpp
// DOS COM2 PORT INTERNAL MODEM DIALER
//#include
#include
#includeint main()
{char c;
ofstream modem("COM2:");
printf("Resetting MODEM\nto Dial");
modem << "ATZ\n";
modem.flush();
c = getchar(); // wait for modem to finish
modem <<"ATDT7500838\n";
modem.flush();
printf("to Hang-UP\n");
c = getchar(); // wait for modem to finish
modem <<"ATH0\n";
modem.flush();
return 0;
}

YIKES! The angle brackets (a.k.a. LT, GT) that HTML uses got chewed up on the INCLUDEs.
I changed them to quotes in the posting instead of playing with the HTML 'pre' tag.* * * * * * * * * * * * * * * * * * *

Anyone can give me a winmodem(s/w modem)
program sample to me.
( Not Linux...... Only Windows... ^^ )
Please.... i can't find...
Thanks A lot! ~*^^*~

If you are using (or have access to a PC with Visual Basic (VB6) with the MSDN disk loaded with default paths taken, I'd suggest looking in:
C:\Program Files\Microsoft Visual Studio\MSDN98\98VSa\1033\SAMPLES\VB98\Dialer
for an example from those loving folk at Microsoft.walt
