Motorola Power 14.4 PCMCIA Modem May Not Dial Twice

• Microsoft Windows 95

SYMPTOMS

When you are using a Motorola Power 14.4 Cellular Modem with Windows 95, you may not be able to dial the second time you try to use the modem.

CAUSE

The initialization string used for this modem in Windows 95 enables a dial suffix. This dial suffix enables transmission of tones after the connection has been made without breaking the connection. One example of how this feature is used is in an electronic banking service. This behavior is also known as staged dialing.

RESOLUTION

Remove and reinsert the modem to dial again. You must repeat this process each time you want to dial again.

To prevent this behavior from occurring, use the following method to disable staged dialing.

NOTE: Microsoft does not encourage or support making changes to .inf files. Therefore, Microsoft Product Support Services (PSS) does not support the following procedure. Although we have tested this procedure and it appears to function as described, you should make a backup copy of the Mdmmoto.inf file in the Windows\Inf folder before you proceed.

1. Use any text editor (such as Notepad) to open the Mdmmoto.inf file in the Windows\Inf folder.

   NOTE: The Inf folder is a hidden folder in the Windows folder. To view this folder, start Windows Explorer, click Options on the View menu, click Show All Files on the View tab, and then click OK.

2. Add the following line to the end of the [Modem16.AddReg] section of the file:

         HKR, Settings, DialSuffix,, ""
   

3. Save and then close the file.

4. Remove the Motorola Power 14.4 modem using the Modems tool in Control Panel.

5. Remove and reinsert the modem.

MORE INFORMATION

The behavior described in this article occurs only with 32-bit communications programs such as HyperTerminal and Dial-Up Networking. When you use a 32-bit communications program, the modem works correctly the first time you dial after starting Windows 95 or inserting the modem, but does not respond on subsequent attempts to dial.
