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.
