HowTo Setup Barcode Scanner

In this HowTo we focus to the Metrologic Product MS9535 Voyager and the Os X Operating System.

To use the Thot library with a barcode scanner, we need to configre the scanner as a serial device and then we need to start a bash script that is able to interpret the data from the scanner. The connection use the bluetooth system, that is a default feature both on the Metrologic Scanner and also on the Apple products.

Essentials to configure the scanner

Configure the scanner
