ActiveSync Using Serial Port Services
Use the wireless Bluetooth serial port connection for ActiveSync just as you would a physical serial cable
connection. You must configure the application that will use the connection to the correct serial port.
NOTE When using a Bluetooth headset with Headset Services, you cannot accept or end a call from the
headset. You must accept or end a call on the MC55.
NOTE By default, COM ports COM5, COM9, COM11, COM21, COM22 and COM23 are Bluetooth virtual ports.
If an application opens one of these ports, the Bluetooth driver activates and guides you through a
Bluetooth connection.
