SYMPTOMS
========

HyperTerminal, the Microsoft Network, or another TAPI-enabled application does
not dial.

CAUSE
=====

This problem occurs when a pre-Windows 95 service provider appears in the
TELEPHON.INI file and precedes the Windows 95 Universal Modem Driver (UNIMDM). A
pre-Windows 95 service provider is one that was built to the Windows 3.1 TAPI,
rather than the Windows 95 TAPI.

WORKAROUND
==========

To work around this problem, perform the following steps:

1. Open the TELEPHON.INI file that is in your Windows directory with a text
  editor (such as WordPad).

2. The Providers section may appear as follows:

     [Providers]
     NumProviders=2
     NextProviderID=3
     ProviderID0=1
     ProviderFilename0=ATSP.TSP
     ProviderID1=2
     ProviderFilename1=UNIMDM.TSP

  Change the above to:

     [Providers]
     NumProviders=2
     NextProviderID=3
     ProviderID1=1
     ProviderFileName1=ATSP.TSP
     ProviderID0=2
     ProviderFileName0=UNIMDM.TSP

The above changes inform the TAPI.DLL file that UniModem is the first provider.

MORE INFORMATION
