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 rst 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 seing 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 seing up outgoing and incoming COM

Ports, read the following section.
