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 Dialing 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 interrupt 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 modem.
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 activity on your
part or because you exceeded your time limit for the day. Try again.
