Using WorldPort
Connecting in different countries may require trial and error until you determine
exactly what you need. This is because a particular country may have multiple
telephone exchange systems that require different configurations. The information
provided below provides some hints for connecting in different countries. Be sure
to have the correct country adapter when you try to connect. See “International
Telephone Adapters” on page 6.
WorldPort Country Select software lets you select a country, then automatically
configures the modem for that country.
To change the modem configuration for another country after WorldPort has been
installed:
1
Open the Start menu and select
Programs/3Com Utilities
.
2
In the WorldPort Country Select Software, locate the country you are connecting
from.
3
Select your country and click OK.
If the country you want to select is not listed, and if the country does not require
modem homologation, set the WorldPort Country Select Software to
USA
.
4
Try connecting.
Hints for Good
Connections
Use the following information when you set up your communications software to
help your modem connect at the highest possible speed:
■
If you have call waiting, disable it. Call waiting generates a tone on the line
that causes results similar to static. It also causes your modem to disconnect or
report NO CARRIER if a call waiting signal comes when your modem is
connected to another modem. Call waiting is usually disabled by using *70 in
your dial string before the phone number.
Contact your phone company if you need more information on how to disable
any call waiting options.
■
Telephone lines with static or noise slow down transmission and require error
correction. If your phone line has a problem with noise, contact your telephone
company to see if they can fix the problem.
■
Don’t use a splitter on your telephone line. A single connection from wall to
modem produces the highest transfer speed.
Because the country selection software provided by Microsoft overrides the
WorldPort country selection, the option to install the Modem WorldPort Utility is
not available under Windows 2000 or XP.
