The Modem Disconnects While Online
•
If you have Call Waiting on the same phone line as your modem, it can interrupt your connection
when someone tries to call you. If you have Call Waiting, disable it before each call. In most
telephone areas in North America, you can disable Call Waiting by preceding the telephone
number with *70 (check with your local telephone company).
You can automatically disable Call Waiting by including the disabling code in the modem’s dial
prefix (e.g., ATDT*70,—note the comma, which inserts a pause before the number is dialed). To
change the dial prefix in Windows 98 HyperTerminal, select Call from the Call menu, click Dial-
ing Properties, check This location has Call Waiting, and select the correct code for your
phone service.
•
If you have extension phones on the same line as your modem, you or someone else can inter-
rupt the connection by picking up another phone. If this is a frequent problem, disconnect the
extension phones before using the modem, or install another phone line especially for the mo-
dem.
•
Check for loose connections between the modem and the computer and the telephone jack.
•
You might have had a poor connection because of line conditions or the problem might have
originated on the other end of the line. Try again.
•
If you were online with an online service, it might have hung up on you because of lack of activi-
ty on your part or because you exceeded your time limit for the day. Try again.
The Modem Cannot Connect When Answering
•
Autoanswer might be disabled. Turn on autoanswer in your data communications program or
send the command ATS0=1 (ATS0=2 if you have Caller ID service) to make sure your modem
in terminal mode.
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 mo-
dem 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 98, you
can have data and fax communication applications open at the same time, but they cannot use
the same modem at the same time.
