Hello

Possible your TAPI device is already busy by other app or service.

You can try to open the from standard windows tool: HyperTerminal.

And we need more information about your Windows versions on problem PCs and on laptop.

If you can please upload modem log files from problem machines. Usual It has name like following:
C:\WINDOWS\ModemLog_*.txt

2. On desktop, i can only wait for call and transfer file. I can't make call even when i tested with HyperTerminal, everything is ok.

Here the modem log file on my desktop:

Hello

Thank you for infomration.

I'm sure that your modem is busy by other service. Please open Administration\Service and try to find and turn off something related with TAPI, modem or RAS (remote access) and etc.

We will try to reproduce your problem on our side.

Thanks for your reply. I checked all services in my computer but found nothing relared TAPI except Telephony service. I can use HyperTerminal or an app. named Dialer in Microsoft SDK to make call or receive call OK.

With TAPI app, i can only set modem in wait for call mode.
Wait for your next reply. Thanks

When trace to the code, in unit nrcommtapi.pas, procedure TnrCommTAPI.Call
after this function:
Code: [Select]
LastTAPIResult:=lineMakeCall(hLine,hCall,
       PChar(fDialableNumber),
       TrOut^.dwDestCountry,@LineParams);
The hLine value always return less than zero.

Hello

Thank you for your information.
You are right the tapi demo from attachment does not help in your problem.

We have done some more deep tests. All works fine on our side.

It seems like your modem device is not compatible with default modem driver that you are using.
I recommend to find and install correct manufacturer driver for your device.

If it is impossible read following:

I see that your modem device does not support following initialization command:
Quote
11-11-2009 13:00:33.406 - Send: ATS7=60L0M1&K3N0X4<cr>
11-11-2009 13:00:33.437 - Recv: <cr><lf>ERROR<cr><lf>

You can try repeat following steps:

1) Run regedit.
2) Open search dialog (Ctrl+F)
3) Search string: SpeedNegotiation_Off
4) Regedit will find registry string value N0
5) Change this value on N1 and save
6) Repeat steps 3,4,5 while search is success

Now you can try to make call again.

Good luck! and Please let me know the result.

Great!!! Now i can make call perfectly. But how can i make the app changes automatically this value when the modem isn't support "SpeedNegotiation"?
Because this app is used by my partner everywhere and not all of them have enough computer knowledge to do such thing like search or modify in registry.
Anyway thanks so much for your response  ;D
