SYMPTOMS
========

If you install two identical modems in Windows 95 and then try to use the second
modem with a 32-bit communications program that supports the Telephony
Application Programming Interface (TAPI), the first modem may be used instead.
The problem occurs if both modems are identified and installed as the same
model.

CAUSE
=====

This problem is caused by the length of the "friendly" name for the modem. You
can see the modem's friendly name (for example, "Practical Peripherals PM288MT
II V.34") in the Modems tool in Control Panel.


RESOLUTION
==========

To work around this problem, remove the second modem and then reinstall it as a
different model. To do so, follow these steps:

1. Click Start, point to Settings, click Control Panel, and then double- click
  Modems.

2. Click the second modem, and then click Remove.

3. Click Add, click the "Don't detect my modem..." check box to select it, and
  then click Next.

4. In the Manufacturers and Models boxes, click a manufacturer and model that is
  compatible with your modem. If your modem is not compatible with another
  modem, click Standard Modem Types in the Manufacturers box and click the
  model that matches the speed of your modem in the Models box.

  NOTE: If you choose one of the standard modems, you may not be able to use
  some of the advanced features of your modem. For example, the option to use
  data compression may not be available.

5. Click Next.

6. Click the appropriate port for the modem, and then click Next.

7. Click Finish.

MORE INFORMATION
================

This problem typically occurs when you install one modem to use with
communications programs, and another modem to use for a different purpose, such
as sending and receiving faxes. If both modems are identical and are installed
as the same model, both modems appear in the Modems Properties dialog box. For
example, if you install two Practical Peripherals PM288MT II V.34 modems in
Windows 95, the following modems are displayed on the General tab in Modems
properties:

- Practical Peripherals PM288MT II V.34

- Practical Peripherals PM288MT II V.34 #2
