Macintosh Computers
Your Tri-Mode Phone has a
signal but you cannot
connect to the data
network.
■ Make sure the baud rate on your
Tri-Mode Phone matches that for the
“QUALCOMM Globalstar Phone
Modem.” Check the baud rate on your
Tri-Mode Phone by selecting
menu >
Features > Data > Baud Rate
, then
change it to 38400 bps if necessary.
■ On your computer, make sure that no
other application is using the modem
port assigned for Globalstar data
service. If another application, such as
Palm HotSync Manager, blocks the
port, disable its control over the port
before attempting a data connection.
Palm Handhelds
The Palm tries to connect
but the Tri-Mode Phone
does not respond.
■ Make sure you have a current Palm
operating system (OS) installed.
Sometimes a newer Palm model
running an older OS version cannot
make data connections properly.
■ Make sure the String field under
Preferences/Modem does not include
any AT commands that the Tri-Mode
Phone does not support for data. (See
“Setting Up a Modem” on page 80 and
“Supported AT Commands” on page
117.)
You have a connection but
your browser cannot access
a Web page, or you are
having authentication
problems not due to user
name/password errors.
■ If Web pages use CHAP (Challenge
Handshake Authentication Protocol),
you may need to upgrade your Palm
OS to work with them.
