It is important that you use a null modem cable; if you use a typical serial cable, the target computer expects a serial device and not another serial port, and you cannot debug the computer.
有一点很重要，那就是要使用零调制解调器电缆，如果您使用普通的串行电缆，目标计算机则期望与串行设备通信，而不是与另一个串行端口通信，这样您就无法调试该计算机。
This article shows you how to set up the debug environment using serial communication port, how to compile modified kernel code, and how to start kernel debugging.
本文介绍如何使用串行通信端口来设置调试环境、如何编译经过修改的内核代码，以及如何开始内核调试。
Listing 2 shows an example of how to launch a VM in debug mode and listen for a socket connection at port 8765.
清单2是一个示例，显示如何在调试模式下启动VM并监听端口8765的套接字连接。
The launch attempts to connect to a VM at the specified address and port, and the result is displayed in the Debug view.
启动试图通过指定的地址和端口连接到VM，结果显示在Debug视图中。
The debug daemon listens on a port for debug engine connections.
调试daemon会监听调试引擎连接的端口。
The port is the port number that the debug daemon is listening on.

If you are running the UI on a multi-user machine, the default daemon port might already be in use by a different debug session.
如果您在一个多用户的机器上运行UI，那么默认的daemon端口应该做好被不同调试操作使用的准备。
For advanced users, you can alter the port number and debug Settings like this.
对于高级用户，可以按如下所示改变端口号和调试设置。
Now when you select the debug option, the debugger attempts to connect to a remote VM at the specified address and port, and the result is displayed in the debug view.
现在当您选择Debug选项时，调试器将尝试按指定的地址和端口连接远程VM，并在Debug视图中显示结果。
