You can make changes to the following options in the Connection section when the virtual machine is powered on or powered off:
• Use physical serial port — Select this option if you want the virtual machine to use a physical serial port on the host computer.Use the drop-down list to specify which available port to use.
• Use output file — Select this option if you want to send output from the virtual serial port to a file on the host computer.Click Browse,and then either locate an existing output file or navigate to the desired directory and type a filename for the file you want to create.
• Use named pipe — Select this setting to set up a direct connection between two virtual machines or a connection between a virtual machine and an application on the host computer.
Use the default pipe name,or enter another pipe name of your choice.The pipe name must follow the form \\.\pipe\ — that is,it must begin with \\.\pipe\.The pipe name must be the same on server and client.
In the first drop-down list,choose whether this is the server or the client.
In the second drop-down list,choose whether the other end is a virtual machine or an application.
In the I/O Mode section,the option called Yield CPU on poll is of interest primarily to developers who are using debugging tools that communicate over a serial connection.Selecting this option can improve performance when the guest operating system is using the serial port in polled mode.Then the virtual machine will yield processor time if the only task it is trying to do is poll the virtual serial port.
If the guest operating system is using the serial port in interrupt mode,do not select this option.

您可以更改下列选项中的连接节时,虚拟机是动力或电源关闭状态：
•使用物理串口-选择此选项,如果您希望虚拟机使用的物理串行端口在主机电脑上.使用下拉式列表可以指定哪些可用的港口使用.
•使用的输出文件-选择此选项,如果您要发送的输出从虚拟串口到一个文件在主机电脑上.单击浏览,然后可以找到一个现有的输出文件或浏览到想要的目录,并输入文件名的文件,你要创建的.
•使用命名管道-选择此设置,以成立一个直接连接两国的虚拟机器或之间的连接虚拟机和应用程序在主机电脑上.
使用预设的管道名称,或者输入另一管您选择的名称.管道名称必须遵循的形式\ \ .\管\ -也就是,它必须开始与\ \ .\管\ .管道名称必须相同服务器和客户端.
在第一个下拉式列表中,选择这是否是服务器或客户端.
在第二个下拉式列表中,选择是否另一端是一个虚拟机器或应用程式.
在I / O模式区段中,选择所谓的收益率的CPU对调查的兴趣,主要是开发谁使用的调试工具,通讯串行连接.选择这个选项可以提高性能,当客户的作业系统是使用串行端口,在接受调查的模式.那么,虚拟机将产生的时间,如果处理器的唯一任务,这是试图做的是调查虚拟串行端口.
如果客户的作业系统是使用串行端口在中断方式,不要选择这个选项.
大概就这意思
