Advertisement Topazz Thread Starter Joined: Sep 16, 2000 Messages: 561 I am unable to dialup to the internet. The computer opens the port, tries to dial then displays the error message: "Disconnected... Error 628: The connection was terminated by the remote computer before it could be completed". I have checked in Modem properties and the modem diagnostic query is successful with no errors reported. There are no exclamation marks in Hardware Device Manager and everything is reported as enabled and working. The log file in Modem properties reports: "Opening the modem device failed with error https://groups.google.com/d/topic/microsoft.public.win32.programmer.tapi/v0x6CT9_MgA 00000020". I am at a loss as to what to do now. I don't have access to the modem drivers so am hesitant to remove the modem from Device Manager and reinstall it because the drivers on the web are older and sound a bit flaky. Running Windows XP Home and the modem is a HSP56 MR by PCtel. Any ideas please? Topazz, Sep 15, 2004 #1 Triple6 Rob Moderator Joined: Dec 26, 2002 Messages: 49,344 Has it ever worked? Any noise on your https://forums.techguy.org/threads/modem-will-not-connect.274415/ phone lines? And are you dialing the right number, with area code if needed?

The computer has had a few problems which resulted in a reinstall of Windows, which then caused a problem with the dialup options being unable to be accessed until SP1 was installed. I have just disabled the internal modem and connected an external modem which has worked and has connected to internet OK. Maybe the internal modem is stuffed? Topazz, Sep 15, 2004 #3 Triple6 Rob Moderator Joined: Dec 26, 2002 Messages: 49,344 Possibly, or maybe its got the wrong driver installed for it or the driver is corrupt. However most external modems outperform internal modems and do not push of the processing of many functions onto the CPU. If the external is a 56K modem then I'd continue using that.

The communication with the SE phones is done through USB/Com driver using AT-Commands. All is working fine with the SE phones, but they are unstable and therefore we have bought CT63 terminals from m2mtec.de modem error 00000020 as replacements. The CT63 terminals have the same AT-commands as the SE phones, but we are having problems with the initial connection to the CT63 terminals. If we run our service with the CT63 the port seems to open fine, but when sending as simple "AT\n" to test the connection we do not get a response from the terminal. If we go to Windows 7 Control Panel, choose "Phone and Modem", Choose the modem properties and do a "Query Modem" on the "Diagnostics" tab the modem response as it should. The Query Modem function sends a "ATQ0V1E0" command and the response is "OK". After doing the "Query modem" we can communicate with the terminal through our C# service and the modem response on the "AT\n" test is "OK". After disconnection the modem an reconnection no response is recieved. We have verified that the COM port settings is the same in the C# service as in the "Query modem" test. Furthermore we have tried to send a "ATQ0V1E0" from our C# service. The problem is the same. Without "Query modem" test we do not get a response and after we get
