GeoPort 1.0, 2.0: High Speed Fax, V.17

I need to disable the high speed Fax feature to dial into an older Fax that will not accept my documents. Page 35 of the "Express Fax/Modem User's Guide" shows a screen shot of the Fax Terminal preferences dialog box. The manual displays an option to turn off "high speed Fax feature". I do not have this option on my screen. I am using Fax Terminal 1.5.1, Power Macintosh 6100/60AV, GeoPort Adapter, GeoPort for Power Macintosh 1.0.

Does the "high speed Fax feature" disabled on the fly, or is there a manual switch to enable and disable high speed Faxing?
Geoport 1.0
The Geoport for Power Macintosh version 1.0 only supports Fax transmission speeds up to 9600 bps (CCITT V.29).

The user's guide for the Express Modem software that ships with the Power Macintosh references high speed Fax capabilities. The option for high speed Fax will not appear in Fax Terminal's preferences window.

The high speed Fax option is only available when Express Modem software is being used with an Apple Express Modem on a PowerBook or Macintosh with an Express Modem installed.


Geoport 2.0
Apple Telecom Software version 2.0 will support high speed faxing (V.17) on a Power Macintosh. The Quadra, and Centris AV Family of computers will not support v.17 speeds.

V.17 fax speed is disabled by launching the Fax Terminal software under the Apple Menu. Under the "Fax" menu, drag down to "Preferences", unselect the box next to "Allow v.17 faxing".
