If Power Macintosh users install the Quadra 660AV and 840AV version of GeoPort software, they will get the error message, "Express Modem cannot be run on this Macintosh", when they try to open the Express Modem Control Panel.
However, you can also get this error message when using older versions of the Power Macintosh version of the GeoPort software. You can verify the correct version by doing a Get Info on the Express Modem Control Panel. The Power Macintosh version will read "Express Modem GeoPort for Power Macintosh (with version number)" at the top of the Get Info window.
The minimum version needed for the Power Macintosh is 1.0 or later, while the Quadra 660AV, and 840AV version is 1.1.2 or later. The most current version of the GeoPort software is available from the Apple Software Updates Web site at
http://www.apple.com/swupdates/
.
Also GeoPort for Power Macintosh 1.0, 1.0.1, and 1.0.2 functions with System 7.5, but you need to use these workarounds:
* 1.0 has two problems with virtual memory
- Network file transfers will fail when Virtual Memory (VM) is on.
- Data connections will fail when VM is on.
* 1.0 and 1.0.1 will crash the computer on restart if there are any faxes
waiting to be sent in the Waiting to be Faxed folder.
* The modem speaker must be turned off at all times through the Express
Modem control panel to prevent intermittent crashing.
In cases, where this error message occurs even with the correct version of GeoPort software installed, a clean installation of system software is recommended. A reinstallation of the GeoPort for Power Macintosh software is needed also.
