Configuring the BitSURFR Pro EZ for 230,400 BPS DTE Rate

If you have a 16650-based COM port, the BitSURFR Pro EZ can be configured for a 230,400 bps DTE rate.  This is accomplished by assuring that you have the proper INF file, mot11b0c.inf. If you do not have this, you will have to uninstall the BitSURFR Pro EZ, delete the existing INF and reinstall the BitSURFR Pro EZ using the following procedure.
  1. Download the mot11b0c.inf file.
  2. From the Windows 95 desktop, open "My Computer".
  3. Also, from the "My Computer" window open the hard disk drive.
  4. From the hard disk drive window open the "Windows" folder.
  5. Select "View" from the pulldown menu bar in the "Windows" window.
  6. Select "Options" from the pulldown menu.
  7. In the "Options" window, click the "View" tab.
  8. Click the "Show All Files" selector.
  9. Click the "Apply" button at the bottom of the "Options" window.
  10. Click the "OK" button at the bottom of the "Options" window.
  11. In the "Windows" window, double click the "INF" folder.
  12. Now you must locate the old BitSURFR Pro EZ INF file usually named   oem1,oem2, etc**. You must then delete this file and uninstall the modem using the applet.
  13. Close the "INF" window.
  14. Now right-click the "My Computer" icon on your desktop and select  properties. Then click on the "Device Manager" tab. Select modems from the list.
  15. Verify that the BitSURFR Pro EZ does not appear in the "Modem" list.
  16. Click the "Refresh" button.
  17. You should now be prompted for a "Disk from hardware manufacturer." Direct the installation wizard to the location where you downloaded the mot11b0c.inf file.
  18. Click ok.
  19. Your new INF file should now be installed.
  20. To verify that it has been installed correctly, select modem properties from the device manager. You do this by highlighting "Motorola BitSURFR Pro EZ" in the "Device Manager" mentioned above and selecting the "Properties" button from the buttons at the bottom of the Device Manager window.
  21. You should now have the 230,400 DTE rate selectable from the list of available rates. If you do not, repeat the above steps to verify correct installation. Send the appropriate AT command to the unit via a terminal application (such as Windows 95's HyperTerminal ).  The AT command that sets the BitSURFR Pro EZ to operate at a DTE rate of 230,400 bps is:

    Once you have issued this command, the BitSURFR Pro EZ will be configured to communicate at a DTE rate of 230,400 bps.  Next, set the DTE rate in your terminal application to 230,400 bps and issue an "AT" to the BitSURFR Pro EZ.   The unit will return an OK. Autobaud is disabled when the BitSURFR Pro EZ is configured for 230,400 bps. All communication with the unit will have to be made at that speed.  To return to a lower speed you will need to issue the appropriate AT command from a terminal application that is set for 230,400 bps.  For example, issuing the AT command:

    will return the DTE speed to 115,200 bps and enable autobaud. (For more information on using AT commands, refer to the BitSURFR Pro EZ User's Guide.) Also, if you plan to use Dial-Up-Networking in Windows 95, you must be sure that this change is reflected in these settings as well. To change your DTE rate for Dial-Up-Networking, follow these steps:
    1. Double-click on the "My Computer" icon.
    2. Double-click on the "Dial-Up Networking" folder.
    3. Click the right mouse button on the entry you wish to edit and select "Properties".
    4. Under this menu, select the "Configure" button.
    5. Here you will see the "Maximum Speed" setting.  Select 230,400 from the pulldown menu.
    6. Click the "OK" buttons until all the screens are closed.

    Windows 95 Dial-Up-Networking is now set up to run at 230,400 bps.

    If you are using a newer version of Windows 95, the procedure may differs slightly. In these newer versions of Windows, the Oem INF files are placed into a sub-directory called OTHER. This directory is still located in the INF directory mentioned above.Also, the file will not be renamed to Oem. It will have a name that matches the product. So the name for the BitSURFR Pro EZ inf will begin with the word "Motorola."  If you have this version of Windows 95, simply delete the BitSURFR Pro EZ INF from this  directory and follow the remaining steps indicated above.
