Bluetooth Virtual COM Ports
Some application programs connect using a virtual COM port
(serial port) when making a Bluetooth connection. To make a
connection possible for such programs, you must first set up
a virtual COM port on the Field PC. Once created, this virtual
port can be used like any other COM port. For example, you
can use a virtual COM port for programs that connect to a GPS
receiver.
When setting up a virtual COM port, you must specify if the
COM port is an outgoing COM port or an incoming COM port.
An outgoing COM port means that the Field PC initiates
communication with the other device. For example, when you
are using a Bluetooth GPS receiver, the Field PC initiates the
request for data; thus, the virtual COM port connecting with
the receiver would be an outgoing COM port.
An incoming COM port means that the other device is initiating
the communication with the Field PC. For example, a desktop
computer might initiate a Bluetooth ActiveSync connection with
the device via the virtual COM port.
For more details about setting up outgoing and incoming COM
Ports, read the following sections.
