modem/DUN? inoperative

The communication program in my Armada 7730 laptop doesn't work. Using Microsoft's troubleshooting program, diagnostics show ATI numbers 5,6 and 7 as errors. Can anyone explain what constitutes these errors and how to handle them. The modem is internal and is shown as VoiceView.

You aren't going to get far with diagnostics unless you have a lot of information 
about your specific modem and chipset, including a manual and a listing of the command 
codes.

The I command (Request Identification Information) causes the modem to report one 
or more lines of text, as selected by the  subparameter 0-9, followed by a 
final result code.

Examples (from a Hayes modem):

5 Reports Country Code parameter (in decimal), e.g.:
ATI5 B5

6 Reports modem data pump model and internal code revision, e.g.:
ATI6 RCV56DPF-PLL L8571A Rev 50.02/34.00

7 Reports modem data pump model and internal code revision, e.g.:
ATI7 OK

ERROR means the modem isn't reporting.

This is not a Win98 problem. Check task manager and make certain no communication 
programs are running. Go to Device Manager and see if your modem is listed without 
exclamation point. You want to see one modem listed. Click properties and hope to 
see the words "This device is working properly". If not, use the Modems applet in 
Control Panel and remove all modems listed under the General tab. From SAFE mode, 
go to Device Manager and remove all devices listed under modem. Then reboot and let 
Windows try and detect the modem. Don't worry if Win98 installs a generic driver. 
If you get the modem working you can install a more specific driver later.

Any further steps depend on whether this computer was working and suddenly quit, 
or one you just got and you know noting about it.

Thanks for your very exhaustive reply which, although not solving my problem, does explain a lot of the arcane stuff behind the scenes. Answers to your specific questions are: 1. Yes, it did work at one time. 2. Yes, it does say that the modem has no problems. 3. DeviceManager shows it works fine. 4. Sys.info shows it works fine. Because of all the positives I thought there may be a simple solution, which is why I submitted it to the forum. Guess I'll have to revise my thinking. A brief history might be in order: Originally came with Win95 which was upgraded to Win98SE some years ago (I love this machine which is the only W98 I have and I prefer it to my other machines with later OS's). When the modem (or DUN) gave up on me I used a PC fax/modem card from Gentech, but because of the poor quality of the cable connection to the card it broke off. Which is why I started thinking of pursuing the original internal modem and hence my resort tothe forum. Again, thanks for your informative comments which are much appreciated. John

It is probably a software modem which were known for failures when they get older, 
or had a high failure rate normally anyway.  Windows can't diagnose parts of the 
modem so it will say there is nothing wrong when in reality the modem has failed. 
 DUN is (Dial Up Networking) which you indicate worked with another modem so we know 
that the software is working.  That leaves a possible driver issue for the internal 
modem, or more probably the modem itself has failed.  Not at all unusual.  You may 
be stuck with using an external or slot modem as I doubt you will easily find an 
original modem.

Thanks for your reply. It helps. C K makes good points also, especially since the 
modem was working and appeared to fail. 

The original modem is a 28.8 right? Is it worth resurrecting? You could use an external 
with an independent DSP thru the serial port and get better performance. It would 
take some of the load off the Pentium II 166 CPU.

Win98 has built in drivers for VoiceView type modems 9600, 14400, 19200, 28800. You 
could try a fresh manual install, as an added modem, checking the do not detect box, 
and choosing your modem from the list. That might resolve the driver question raised 
by C K. 

Sometimes software just seems to get stuck or confused. VoiceView modems have a voice 
mode and a data mode. A list of commands supported will be in the registry from the 
original install at

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Modem

Highlight the key for the internal modem, probably 0001, in the left pane and there 
will be information about the modem in the right pane, including the .inf file name.

Below each key are subkeys. The Init subkey gives the initialization string that 
is being sent to the modem each time you make a connection. Other subkeys are AT 
commands. You can use Win98 utility HyperTerminal to send commands directly to the 
modem and see if it responds, or add a command to the Extra Settings area of the 
Advanced Connection Settings dialog box to force data mode after initialization, 
for example.

Thank you both. I will try the suggested steps and, if unsuccessful, will call it a day and look for a decent PCMCIA. You mention an independent DSP?? that could be attached to the serial port (9 pin?) at the back. Could you fill me in on this, as such a connection would be more suitable for me than the PC card on the side.

An external modem that connects to the serial port (not USB), with its own onboard 
controller chip and Digital Signal Processor, has some advantages in your situation. 
The VoiceView modem uses cpu cycles to perform functions like data compression and 
error correction. With an external modem there are no proprietary hardware, slot 
configuration, driver issues, IRQ or port conflicts. You would get 56K and V.92 performance.

The system requirements are any computer with a RS232 serial port, including Mac 
OS, DOS, any version of Windows, Linux or Unix.

If the computer dies, you take the modem with you to the next one. You can easily 
use one modem with several different computers. It has its own power supply, so doesn't 
add load to the one in your laptop or add to the heat.There is circuitry to handle 
power glitches and lightning. If you learn to read the indicator lights, you will 
always know what is happening, and if things freeze up you can turn off and restart 
the modem without rebooting the computer.
