The Modem Doesn't Work With Caller Id; Fax And Data Software Can't Run At The Same Time - Multi-Tech MT9234ZBA User Manual

The Modem Doesn't Work with Caller ID

•
Caller ID information is transmitted between the first and second rings, so if autoanswer is turned off
(S0=0) or if the modem is set to answer after only one ring (S0=1), the modem will not receive Caller
ID information. Check your initialization string, and if necessary change it to set the modem to
answer after the second ring (S0=2).
•
Make sure that you have Caller ID service from your telephone company.

Fax and Data Software Can't Run at the Same Time

•
Communications devices can be accessed by only one application at a time. In Windows 2000 and
higher, you can have data and fax communication applications open at the same time, but they
cannot use the same modem at the same time.
