You may hear a brief handshaking as the modem tries to establish a connection.
Normally, your LAN+Modem card waits for a dial tone before dialing. In some
cases, however, a modem cannot detect a dial tone even when voice calls can be
completed. This problem can occur when:
Dialing into a standard telephone network using nonstandard dial tone
conventions
Placing a call from a country outside of the United States, where a different dial
tone is used
Dialing through a business or hotel PBX or a voice-mail system that indicates
new mail with a unique dial tone (travelers often find that hotel PBXs have
unique dial tones)
Using telephones (such as cellular telephones) that require you to press a
button before the dial tone can be heard
If you cannot obtain a normal dial tone following the procedures provided for your
phone, you may have to reconfigure the dialing options for your communications
package. Most packages have a Wait for Dial Tone Before Dialing option that you
can enable or disable if your modem is having trouble detecting a dial tone. You
must disable this option to permit blind dialing.
Users in the USA can use the LAN+Modem card to establish a cellular connection
to a remote site. Before attempting to establish a cellular connection, you must
obtain a proper cable for your cellular phone.
