Open Transport: MegaPhone & Other Apps Activate AppleTalk

I have a Power Macintosh 7500/100 with a GeoPort Telecom Adapter, and I'm using Telecom 2.1 software. The GeoPort Telecom Adapter is connected to the computer's modem port.

After doing a clean install of the system software and installing the Apple Telecom 2.1 software, while troubleshooting, I was able to use the MegaPhone demo software version 1.0.2ST successfully. I then installed the released MegaPhone software, version 1.0.2, selected the modem port in the AppleTalk control panel, and made AppleTalk inactive.

When launching MegaPhone, AppleTalk automatically becomes active, and I'm unable to use the MegaPhone software. What is wrong?
Issue
-----
Cypress Research has reported, when launching the released version of the MegaPhone application, it checks to see if AppleTalk is active or inactive. When this check is made, AppleTalk automatically becomes active.

This issue has also been noticed with some other applications which make the same system check and automatically activate AppleTalk such as some versions of the following: Adobe Pagemaker, Macromedia Freehand, Quark XPress, Global Village Fax Software, and others.

MegaPhone Workaround
--------------------
If a user calls Cypress with this issue, Cypress will send them a modified version of MegaPhone which does not check AppleTalk for being active or inactive.

Resolution
----------
Open Transport version 1.1, installed with System 7.5 Update 2.0 corrects this issue.
