Some services are hardware-dependent; this computer cannot provide the fax service unless it
has a physical fax modem, for example. Some Bluetooth services use virtual “hardware”. The
Bluetooth Serial Port service, for example, does not use a physical port on this computer. Instead,
it creates virtual serial ports that Windows applications can see and use as if they were actual
physical ports. Each Bluetooth service that this computer is capable of providing can be started
automatically when Bluetooth starts. Each service can be set up to require security measures
before allowing a remote Bluetooth device to connect. Bluetooth services require a Bluetooth
application on the remote device; services and applications usually have coinciding names; i.e.,
there is a Bluetooth Fax Service and a Bluetooth Fax Application.
The services supported by Bluetooth are:
•
Bluetooth Serial Port—a wireless connection between two devices. This connection can be
used by applications as though a physical serial cable is connected to the devices.
•
Dial-Up Networking—allows a device to use a modem that is physically attached to another
Bluetooth device.
•
Fax—allows a device to send a fax using a remote Bluetooth cell phone, modem, or computer.
•
File Transfer—allows a device to perform file system operations on another Bluetooth device;
browse, open, copy, etc.
•
Headset—allows a Bluetooth headset to be used as the audio input/output mechanism for
another Bluetooth device, such as a computer or cell phone.
•
PIM Item Transfer—allows two Bluetooth devices to exchange Personal Information Manager
data such as business cards, calendar items, e-mail messages, and notes.
•
PIM Synchronization—allows two Bluetooth devices to synchronize Personal Information
Manager data.
•
Network Access—allows a device to access a Local Area Network via a second Bluetooth
device that is physically connected to the network or allows a remote device to become part of
an ad-hoc network provided by the Bluetooth server.
•
Audio Gateway—allows the microphone/speakers on Bluetooth device (typically a computer)
to be used as the audio input/output mechanism for a remote Bluetooth device, such as a cell
phone.
All Bluetooth servers do not necessarily provide all of these services. For example, network
gateways may provide only the Network Access service.

The Bluetooth Connection Status dialog box displays information about the state of a connection
and provides a means to disconnect an active connection.
Display the Connection Status dialog box:
in My Bluetooth Places, from the Folders pane,
select a device, and then, in the right pane of My Bluetooth Places, right-click a service name and
select “Status” from the shortcut menu.
