如何与硬件链接在硬件随附的手册中进行了说明.我们不知道它是什么硬件，您没有告诉我们.

How to link with the hardware is explained in the manual that came with the hardware. We don''t know what hardware it is, you did not tell us.

通常，条形码读取器模仿键盘的行为，因此没有特殊要求来处理其输入.但是，如果您的设备是异国情调"的，那么您可能需要编写一些代码(制造商应至少提供一个API).

Usually barcode readers mimic the keyboard behaviour, hence there aren''t special requirements to handle their input. However, if your device is ''exotic'' then you may need to write some code (the manufacturer should then provide at least a API).
