- SYMPTOMS
- ========
-
- When you attempt to install a Zoom Comstar 14.4 or 28.8 Plug and Play
- modem in Windows 95, you may experience one or more of the following
- problems:
-
- - If the COM1 and COM2 ports are already installed and listed in Device
- Manager when you install the modem, the modem may be configured to use
- the COM5 port. This problem is known to occur even when the COM3 and
- COM4 ports are not already installed and listed in Device Manager.
-
- - After you install the modem, the serial port that the modem is
- configured to use is not listed in Device Manager. To determine which
- serial port the modem is configured to use, click the modem in
- Device Manager, and then click Properties.
-
- - You may be unable to communicate with the modem using the ECHO command
- from a command prompt in Windows 95 unless the real-mode drivers that
- came with the modem are installed in the Autoexec.bat and Config.sys
- files.
-
- - You may be unable to establish a connection using the modem with
- HyperTerminal, Dial-Up Networking, Phone Dialer, or any other 32-bit
- communications program.
-
- CAUSE
- =====
-
- These problems are known to occur with the Zoom Comstar 14.4 and 28.8 Plug
- and Play modems when they are used with Windows 95. These problems are not
- caused by a problem in Windows 95.
-
- RESOLUTION
- ==========
-
- For information about resolving these problems, please contact Zoom
- Telephonics.
-
- MORE INFORMATION
- ================
-
- When you install a Zoom Comstar 14.4 or 28.8 Plug and Play modem in Windows
- 95, the modem will not be configured to use the COM3 or COM4 ports even if
- those ports are not already installed and listed in Device Manager. The
- modem may still function correctly with 32-bit communications programs when
- configured to use the COM5 port, but it may not function correctly with 16-
- bit communications programs.
-
- After you have successfully installed the modem, you may be unable to
- communicate with the modem using the ECHO command from a command prompt in
- Windows 95 unless the real-mode drivers that came with the modem are
- installed. When you use real-mode drivers for your modem in Windows 95, you
- are unable to take full advantage of the 32-bit communications architecture
- that is available. For this reason, using real-mode modem drivers in
- Windows 95 is not recommended.
-
- After you have successfully installed the modem, you may be unable to
- establish a connection using the modem with 32-bit communications programs.
- This problem occurs when the initialization strings for the Zoom Comstar
- modem in the registry are incorrect. For example, one of the initialization
- strings for the modem should be:
-
- AT&FE0V0&C1&D2S95=47S0=0<cr>
-
- In some cases, the initialization string that is actually placed in the
- registry is:
-
- AT&FE0V0&C1&D2S95<cr>
-
- When the initialization strings for the Zoom Comstar modem are truncated
- in this manner and you attempt to establish a connection using a 32-bit
- communications program, the Modemlog.txt file may indicate that the correct
- strings were sent to the modem.
