Re: Reading barcode
A Barcode can be displayed a font. There is no need to have a code typically to do this, you just need a barcode font. Then the output from a barcode reader is ASCII characters. The encoding for barcode 3 of 9 for example is to surround your text with asterisks. As such 1234 becomes *1234*. If you type that in 3 of 9 font, most barcode readers are programmed to read it.

To keep the plot moving, that's why.

Re: Reading barcode
I bet you have a specific barcode reader in mind, why not read the manual?
Just guessing now but for me the most likely interface is USB and that the reader show up as a serial port device.
