I tried to do a modem HotSync
operation, but it did not
complete successfully.

Make sure you are not running another program, such as
WinFax, CompuServe, or America Online that uses the
serial port you selected in the Setup dialog box.
Make sure your modem resets before you try again. (Turn
off your modem, wait a minute, then turn it back on.)
On a Mac computer, check the following:
Make sure Modem is selected on the Serial Port Settings tab
in the HotSync Software Setup window.
You may need to select a different Modem type or enter a
Custom setup string on the Serial Port Settings tab. Most
modems have a setup string that causes them to send initial
connection sounds to a speaker. You can turn on the Modem
Speaker option and use these sounds to check the modem
connection.
Make sure you are not running another program, such as
America Online, fax or telephony software, or AppleTalk
networking that uses the serial port you selected in the
Serial Port Settings tab.
Make sure your modem resets before you try again. (Turn
off your modem, wait a minute, then turn it back on.)
Check the following on your handheld:
Confirm that the telephone cable is securely attached to
your modem.
Make sure the dialing instruction dials the correct phone
number.
If you need to dial an outside line prefix, make sure you
selected the Dial Prefix option on your handheld and
entered the correct code.
If the telephone line you are using has Call Waiting, make
sure you selected the Disable call waiting option under
Modem Sync Phone Setup on your handheld and entered
the correct code.
Make sure the telephone line you are using is not noisy,
which can interrupt communications.
Check the batteries in your modem and replace them if
necessary.
