7.5 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 (for example,
ATDT*70,
—note the comma,
which inserts a pause before the number is
dialed). To change the dial prefix in Windows 95
or 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.
