13.3. Barcode Reading Using the Virtual COM Port

13.3.1. Outline

Barcode reading using the virtual COM port is supported on the BHT-700 series.

For greater convenience, this function is available for use in conjunction with kbifCE. For more

information on kbifCE, see the kbifCE user's guide (available for download on the DENSOWAVE QBNet

website).

Using this function it is possible to obtain reading data as if it were being received through a COM port.

For applications, it is equivalent to a reader being connected to the communication port (COMx). Using

COM, barcode reading data can be used by multiple applications.

13.3.2. Programming

Port number 5 is allocated to the virtual COM port used for barcode reading.

Barcode reading mode and the types of barcodes that are allowed to be read are designated by the

kbifCE.

A comparison of the functions of Win32 API when using a general COM port and a virtual COM port for

barcode use is as follows:

Win32 API General COM Virtual COM used for reading

CreateFile Open COM port ←

CloseHandle Close COM port ←

ReadFile Read received data Read data

GetCommMask Obtain type of wait event ←

SetCommMask Set type of wait event ←

Treat completed reading event as

receiving event.Non-reading events

invalid.(*1)

GetCommTimeouts Obtain timeout value ←

SetCommTimeouts Set timeout value ←

Non-receiver side timeouts invalid.(*1)

WaitCommEvent Wait for event ←

Non-receiving events invalid.

(*1) An error will not occur.

The following functions are not supported. If operation is attempted, no function will be executed.

13.3.3. How to Use

Start up kbifCE and set the destination for the virtual COM port (for further details see the kbifCE user's

guide).
