How do you get FNC 3 in ASCII? I wanted to use that for creating a function when press, configuration will be set from barcode manual.

For example

BarCodeComm.Output = Chr$(27) & Chr$(128) & Chr$(29) & "CD000"

I assume ASCII 128 might be FNC 3 but it doesn't work as intended, any clues?

Update: I found out my FNC3 is ASCII "201" provided by this link https://github.com/lindell/JsBarcode/issues/162 and I tried the barcode image provided, so I decided to code shown below

BarCodeComm.Output = Chr$(201) & "CD000"

Is still doesn't work, I don't think is possible to read and configure scanner function in code specifically for my barcode scanner as it doesn't provide set and end.

If there is anyway to configure in code (any language) for me to reference please do assist. Thanks

Accurate specifications depend on the descriptions in the scanner's user manual and programming manual.

Chr$(128) is supposed to indicate FNC3, but possibly the combination of the first three bytes including it probably points to FNC3.

Because Chr$(27) is the ASCII ESC and Chr$(29) is the ASCII GS, both of which are out of the Code 128 code table.

Please check the user manual and programming manual of the scanner.
