your modem is assigned to Serial USB (COMx), rerun the
Hardware Wizard and choose Select from a list instead of
Autodetect. Then, select Serial USB (COMx) as the COM
port.
Error Message on Your Handheld Computer
If the error message "Connection Not Established" appears
on your handheld computer, check that the COM port
setting in either your HotSync or ActiveSync software,
matches the setting on the port replicator, see "Verifying
Devices are Installed" on page 11 to verify the COM port
setting on the port replicator.
You may also want to try reducing your baud rate setting in
Hot Sync or Active Sync.
