IMPORTANT INFORMATION NOT CONTAINED IN THE ORIGINAL READ ME:

- Modem performance:

After you have updated the modem you may notice that the connection speed that is reported when you first establish a connection may be lower than it was prior to the upgrade, however the modem throughput will be at least as good and often better than before the upgrade.  Throughput is the measure of how quickly a certain amount of data is transferred from one modem to another.  It is important to remember that the connection speed that is reported is only the initial connection speed.  The modems will adjust their communications speed as line conditions require.  A faster connection speed does not necessarily indicate a higher throughput, factors like resending data due to noise on the phone lines will lower overall throughput.  This is discussed in more detail in TIL article 30734, "V.90 Protocol: Connectivity Discussion" and TIL article 24482, "56Kbps Modems: Getting The Fastest Connection"  To view these articles, point your web browser to:

- PowerBook G3 Series:

When you are updating a modem in a PowerBook, connect the PowerBook to the AC adapter to guarantee an uninterrupted supply of electricity to the PowerBook.

- PowerBook G3 Series Modem Extension, v 1.0.1

The PowerBook G3 continues to supply power to the built in modem for 30 seconds after an application has used the modem.  This minimizes the time it takes to start the next connection.

With version 1.0 of the modem extension, if the PowerBook G3 is put to sleep immediately after terminating a connection, the modem will continue to draw power which reduces the amount of charge left in the battery.

Version 1.0.1 corrects this problem by turning power off to the modem when the PowerBook G3 is put to sleep.

All PowerBook G3 Series computers with the Apple built in modem should upgrade to version 1.0.1 of the modem extension.

Installation:
1.  Drag the PowerBook G3 Series Modem extension on top of the System Folder.
2.  You will be informed that extensions need to be placed in the Extensions Folder.  Click OK.
3.  You will be informed that an extension with the same name already exists in the Extensions Folder.  Click OK to replace the existing extension.*
4.  Restart the PowerBook.

*  If the name of the existing modem extension is not exactly the same as the name of the newer extension it will not be replaced by the newer extension as indicated in step 3 above.  If you do not see the dialog described in step 3, please manually drag the older modem extension out of the Extensions folder and onto the Desktop.  This will guarantee that the newer modem extension will be used.  The older extension may be deleted after the PowerBook is restarted.

- Communicating at an unknown rate:

If your modem originally supported only the K56flex protocol (shipping in the first PowerBook G3 Series computers), the original modem script (CCL) does not include all the possible V.90 rates.  Updated and localized modem scripts will be posted in the future.  The Z version of the Apple Modem Updater 1.3 contains US-English V.90 modem scripts that can be used in the interim.
