Your initialization string is broken. Although you may have already found out that by going to:

Control Panel => Phone and Modem => Select your blackberry modem => Properties => Change Settings Button => Advanced Tab => Extra initialization comments, it should say:


what is a very subtle and difficult to notice problem is that your quotation marks are not actually quotation marks.


Type in the above string manually, without copy and pasting from any websites, and you should be good to go.

Detecting This Is The Problem

There are two steps for confirming this is the problem (assuming you haven't fixed it already after reading this page)

Control Panel => Phone and Modem => Select your blackberry modem => Properties => Change Settings Button => Diagnostics tab, press the "Query Modem" button and you will probably see things:

ATQ0V1E0    Success

AT+GMM    RIM BlackBerry Device 5001234



Seeing that is a good sign that your computer and BlackBerry are in fact talking to each other. Next, leave that window open and try to connect the usual way you try. After you get the Error 692 message:

  1. Go back to that modem properties window.
  2. Click the "View log" button. 
  3. Scroll down near the bottom of the text file that opens.
  4. See if you notice something like the following:
