"A 32-bit TAPI program may not be able to access installed modems. Even though there is a modem installed, the program may start the Install New Modem Wizard, or may not allow you to select a modem.

For example, when you start the Make New Connection Wizard in Dial-Up Networking, the Install New Modem Wizard may start even though a modem is already installed."
This example is exactly what's happening!
The instructions go on to say re-extract the unimdm.tsp file. I did that and later I also re-extracted the unimodem.vxd file.

And, I've removed the modem and the Com ports and let Win98SE find them again -- done this a bunch of times. According to the settings in control panel, the modem is installed on Com 2, Interrupt Request 9.

I've tried renaming the telephon.ini file and having it recreated -- it was the same.

Have you got any suggestions? I need this thing to work outside of AOL.
