Answer: Ensure that you are NOT using any other
software application that may be setup to use the same
COM port. Common faxing applications like Winfax Pro
& ProComm may be configured to use the same COM
port. If they are setup to use the same port, exit the
conflicting application and re-start the HotSync
operation.
If it still is not working correctly, make sure that you have
the proper COM port selected in the HotSync control
panel. To verify the COM port setting:
1. Click on the HotSync manager icon in the tool bar.
2. Click "Setup"
3. Click on the "Local" tab.
4. Use the drop down arrow to select the proper COM port
and press "OK".
