The HyperModems are no speed slouches. I liked the two-headed serial cable that came with the external modem, ready for both types of serial ports without an extra adapter. The external HyperModem doesn't support voice or fax on demand, but its easier installation could make it the better choice for many federal users. The internal HyperModem comes in voice and nonvoice versions. I tested the voice version because of its potential as a reasonably priced telephone and fax management call center for small offices.
Users can run into port conflicts when installing cards.
That made configuration easier, because the card didn't have to be removed repeatedly from the PC to change default settings. The most installation help came from the utility software. The utility quickly detected free COM ports and notified me before installation began. The Amquest voice and fax software works with BitWare from Cheyenne Software Inc. of Roslyn Heights, N.Y., and is only for Microsoft Windows environments. These messages can guide callers to any fax documents or voice mailboxes you might wish to configure.
