For Windows 3.1x 


1) Click on "File"


2) click on "Run"


3) Enter the directory path and file name i.e.


"c:\temp\v9ibm556.exe"


4) Then click "OK"


5) Follow prompts





For OS/2


1)Open the System folder on the desktop


2) Open the Drives folder

----------------------------------------------------------------


1. Saving Your New V.90 .INF File(s) For Future Installation





The INF file supplied by the V.90 upgrade application is


necessary for the correct operation of your modem using the new


V.90 specification.





The new INF file is located in the same directory where


this ReadMe.Txt file is located, usually in c:\v90\v9ibm556. In some


cases, there will be multiple .INF files listed. The inf has the same 


name as the original inf but the  creation date is May 28, 1998 and 


the version number is 1.12.11 instead of March 13, 1998 and 1.0.05.





     IBM 56K PC Card Modem     mdmibm02.INF





We recommend you save the .INF file specific to your modem


to a blank disk and store it in a safe place. These V.90 .INF


files will be required if you should need to reinstall your modem


in the future.





----------------------------------------------------------------


2. If you Encounter Errors While Running PFWIN.EXE





The V.90 upgrade application uses the PFWIN.EXE utility to


upgrade your modem. When using PFWIN.EXE, you may encounter


errors during the upgrade.  PFWIN.EXE has been designed to


protect your modem from damage whenever possible and will


exit if any errors are encountered.





You would need to run the PFWIN.EXE program again only if a problem


had occurred as the V.90 program used PFWIN.EXE to flash the


modem firmware.





Be sure your modem is inserted, configured, and initialized


properly. Exit Windows and reboot, then run PFWIN.EXE again.





Be sure PFWIN.EXE is being run from your hard drive.  If you


run PFWIN.EXE from a floppy drive, your modem will not be


updated correctly. Confirm that the PFWIN.EXE and PFWIN.HLP,


along with the ?????.UPF, ?????.UPG, and ?????.UPP files for


the V.90 upgrade are located on your hard drive before running


PFWIN.EXE.  The V.90 upgrade application automatically copies


these files to your hard drive before running PFWIN.EXE.





----------------------------------------------------------------


3. Upgrading Multiple Modems





To upgrade multiple modems, you can use the PFWIN.EXE utility


supplied. When the PFWIN.EXE utility is run by itself, no


information is updated on the computer that is updating the


modem. This process allows multiple modems to be updated to


the V.90 standard.





Steps to use the PFWIN.EXE utility are as follows:





  1. Confirm that the PFWIN.EXE and PFWIN.HLP, along with


     the ?????.UPF, ?????.UPG, and ?????.UPP files for the V.90


     upgrade files are in a directory on your computer's hard


     drive.





  2. Run PFWIN.EXE and follow the directions within that


     appear on your computer screen.





----------------------------------------------------------------


4. Updating Multiple Computer Systems Where Modem Is Installed





NOTE:  For Windows 95 or Windows NT 4.0 users only.


       Windows 3.x users do not need to worry about updating


       the computer.





When you run the V.90 Upgrade, the V.90 upgrade files


are copied to your computer, and minor modifications are made


in the Windows Registry under Windows 95 and Windows NT 4.0.





These registry changes will be made only to the computer


used to perform the upgrade.  If you use a V.90 upgraded modem


on a different computer, you may experience minor problems


with the modem's CONNECT messages.





To update another computer system, run the V.90 upgrade


application on the computer requiring the update to modify the


registry entries. When the V.90 application runs the PFWIN.EXE


utility, select the cancel button to abort the modem upgrade.


The registry is now updated for your modem on the computer that


the V.90 upgrade application was run.





----------------------------------------------------------------


5. You Must Have V.90 on Both Ends of the Connection





In order to make a V.90 connection at up to 56k bps, the modem


you are connecting to must also support V.90. Contact your Internet


Service Provider (ISP) to be sure it supports the V.90 standard.





If the host modem that you are connecting to supports x2, but not


V.90, your modem will make attempt to make an x2 connection at up to


56Kbps. If neither V.90 or x2 is possible, the modem will connect at


a standard V.34 connection of up to 33.6k bps.





V.90 and x2 modems are capable of receiving data at up to 56Kbps from


compatible V.90 and x2 service providers, and transmitting data at up


to 33.6Kbps.  Public networks currently limit maximum download speeds


to about 53Kbps.  Actual speeds depend on many factors and are often less


than the maximum possible.





----------------------------------------------------------------


6. If More Than One Modem is Installed





The V.90 upgrade autodetect may not find the correct modem to


upgrade if more than one modem is installed on your computer.


The upgrade utility cycles through the COM ports to locate


upgradeable modems, and stops looking when it locates one.





Use the IBMPFWIN pull-down menu to select the COM port of the


modem you plan to upgrade.





----------------------------------------------------------------


7. Restoring x2 Modem Operation





This V.90 upgrade application provides the latest operating code


for the V.90 standard. Your modem with the new V.90 upgrade


should perform as well as the original x2 configuration. In


addition, you will have the newest features that are available


with the V.90 standard.





In the interest of creating the best products for our customers,


we believe that the V.90 standard will enhance the connectivity


of your modem with those around the world.  However, in the event


that you are experiencing problems with your new V.90 modem,


you have the ability to restore your modem to the original


x2 configuration.





The process to restore your modem to its former x2 operation can


be done simply by using the original V.90 upgrade application while


specifying the command line parameter /x2.





Click on "Start", then "Run ". Enter the directory path and the 


file name adding the /x2 command line parameter.


 i.e. "c:\v90\v9ibm556\v9ibm556.exe /x2" and then click "OK".





If the application was started correctly using the /x2 parameter,


a verification that x2 will be restored is displayed on the bottom


of the first screen to appear, next to the current version of the


application. To insure x2 operation, please verify that the text


following the version information is displayed as /x2.





----------------------------------------------------------------


8. Additional AT Commands For V.90 Operation





Listed here are two additions to the command set for the


operation of your modem using the V.90 standard.





These two additions  AT&U  and  AT&N  are not listed in the


manual supplied with your modem, and are listed here for


your reference.
