7400B and 7400B Plus Data Module

Terra Nova® V1.1.1

White Knight V11 (MacIntosh package)

For those PC packages used to dial voice calls, the modem configuration must be set to PULSE

(P)(even though the 7400B Plus will use Touch-Tone for voice calls). If given a choice, set modem type to HAYES.

Note: While the 7400B Plus supports simultaneous voice and data, the packages listed here support alternate voice/data dialing only. Voice dialing packages interfere with data operation by remapping the COM port or by hanging up the data call.

You can dial a data call while on a voice call. In all cases, the linked telephone will work.
