Default Any Tapi/Dun/Modem Experts Question

On Tue, 25 Oct 2005 01:00:36 +0000 (UTC), nonewbie
put finger to keyboard and composed:

cannot get dun to work with aztech mdp3880-w(u) modem.

installed latest drivers, install went fine. "more info" reported info
from the modem.

When I try to dialout using dun i get : "error 633- modem is not
installed or configured for dialup, double click on the modems icon in
control panel"

When I do the above, it tries to reinstall the modem drivers,even though
they have already been installed.

Tried on of MS's solutions and rebuilt telephon.ini, still no go. Also
did their registry fix for telephon.ini

tried uninstalling and reinstalling drivers and modem still no problem.
Modem now assigned to com3 IRQ 10

in my Dell dimension bios, there is a section for all the irqs where u
set it to either available or reserved, but I was told that this is only
for non-plug and pray modems and I got a message from windows saying
this is plug and pray modem. IRQ is currently marked available in bios.


Your modem uses a Rockwell/Conexant HCF (controllerless) chipset. It's
not a bad performer, at the very least it uses much less CPU power
than Conexant's softmodems (HSF).

These are Conexant's generic drivers for HCF modems:

This is the entry point for all other drivers:

Your modem's properties, commands, and responses are located at this
registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\Class\Modem\000n

How does yours look?

If this key has a problem, then check the contents of the modem's INF
file. That's where the setup info comes from.

Can you set up a comms session using HyperTerminal?

Here is a FAQ that may have useful info:
http://www.conexant.com/support/md_faqs.html

IIRC, there is a special procedure to uninstall HCF/HSF drivers.

Here is an excerpt from the FAQ:

================================================== ===================
I would like information on drivers to install for both modem
enumerator and modem.

The installation instructions are packaged with the generic drivers.
Please refer to the readme.txt file for instructions on how to remove
and install the drivers.
