推荐答案

有没有好的，简单的方法：

There is no good, easy way:

• A 好办法是解决其他应用程序;或者，如果这是不可能的，写一个过滤设备驱动程序（类似parport驱动程序，但串行端口，而不是并行口），这将坐在串口硬件驱动程序的顶部，这将暴露多个连接点（一个由使用其他应用程序，它贯穿于底层的真正驱动力，并通过自己的应用程序使用的另一个'后门'......真正的司机只能看到一个客户端，即过滤驱动至极坐在它上面）


• 的轻松办法就是核弹（强行终止）其他进程。

• A good way is to fix the other application; or if that's impossible, to write a filter device driver (similar to the parport driver but for serial ports instead of parallel ports) which would sit on top of the serial port hardware driver and which would expose more than one connection point (one used by the other application, which passes through to the underlying real driver, and another 'back door' used by your own application ... the real driver would only see one client, i.e. the filter driver wich sits on top of it)
• An easy way is to nuke (forcibly terminate) the other process.
