I am trying to install 4 PCI conexant modems in a Windows 2000 Advanced Server machine. Only the modem whose driver installed last works, for the others the query modem command returns 'Can't Open port' Error.
Can Any one help me out on this.
I am so desperate

Soft modems and 'DSP' modems are generally designed such that only 1 modem is supported - the limitation being in the modem driver design for the chipset.

You could combine different chipsets to get to 4 soft/DSP modems; otherwise, you'll need hardware-controller based modems (Conexant's ACF, or Agere's Venus, or some USR models).
www.modemsite.com/56k/chipset.asp

I haven't tried installing a Conexant HCF and a Soft56 at the same time in same machine - so not sure if it would work. Come to think of it, I haven't tried installing an Agere DSP and Softmodem at same time in same machine, although I would expect that combo to work.

Are all these modems going to be making high-speed (>33.6k) connects? (You may be able to find used V.34 multi-modem products - 4 modems on a single card....)

Aloha! Richard.

Are you wanting to Multilink these modems or use them one at a time? There is a mutli modem pci card for this OS,some with up to 8 modems.

Richard,
thanks a lot for enlightening me about the nature of software modems.
Charles,
I know that option but I am trying to use the modems I have allready got from my other 4 PCs which doesn't need the modem. I live in the poorest country in the whole world ( 100 USD GDP per capita for your information) so I have to economize on everything.

Oh - sorry, I didn't notice the country!

What you might try - find other PCs that have different chipset modems and trade some of the ones you have for them.

(Also - some 5.x (V.90) drivers for the LT Win (Agere) chipset have been used to support more than 1 modem in same machine. However, this was never "officially" supported - and not all who tried had success. Agere made clear that support for more than 1 modem was a design goal - and is not supported.)

Aloha! Richard.

It turned out that almost all modems people got around here are connexant. I have one NetoDragon modem which worked along with one connexant modem.
I have tired a connexant modems which looked different in the other devices other than the connexant chip but that combination doesn't seem to work. What do you think of it, different modems but with the same connexant chip?
