Mohsen,
Greetings and hallucinations from just north of Fantasy Land (Washington,
DC)!
Why do you want two modems in the first place? That being said. It might be
possible to hook up one controllerless and one hardware modem at the same
time, but it seems to be a lot of work for not much gain.
Peace,
Paul

As I stated in my other post, I don't think it is possible to do this
for soft or controllerless modems. OTOH, if your internal modem is a
full hardware modem (ie one with a controller and DSP implemented in
hardware), then it may be possible to install two of them. This is
because these modems do not require a driver, only an INF file.

If you can be more specific in your description of your Acorp modem
(eg model number, chipset part numbers, modem diagnostic info in
Control Panel), then we may be able to ascertain which flavour of
modem you have.
