推荐答案

按钮时打开现金抽屉一般原则：

现金抽屉通过COM1等端口连接到计算机，计算机通过端口的物理线路发送信号。

要发送的信号取决于它所连接的端口它使用哪个端口信号。

没有这方面的知识，就不可能显示任何代码。



当你知道细节时，谷歌用于端口通信和此信号处理的代码。

General principle:
The cash drawer is connected to computer via a port like COM1, and the computer send a signal trough a physical line of the port.
The signal to send depend on the port to which it is connected and which port signal it use.
Without this knowledge, it is impossible to show any code.

When you know the details, Google for code for the port communication and this signal handling.
