【求助】如何安装COM端口的驱动？

renjieah

  因为要使用COM端口所以想在PE环境下给它安个驱动，
可用驱动精灵时提示无法为PORTS加载驱动。
到底要怎样才能为COM端口安驱动？

yichya

需要变动很大一部分。
比如要复制SERENUM.SYS、SERIAL.SYS、SERIALUI.DLL
要在TXTSETUP.SIF中加入条目等。
具体我也不大清楚。

renjieah

TXTSETUP.SIF是什么？
我机子上没有这个文件啊
或者哪有详细一点的也行
谢谢了

WinPE 2.0 will auto-detect PNP0501(COM) and PNP0401(LPT1) , you just need use addcom1.cpp to add a symbolic link for COM1.



Here I paste addcom1 source code here, you may use VC++ any version to compile a new addcom1.exe

* Adding Symbolic Names of Serial Ports to Windows PE



Windows PE does not create symbolic names such as COM1 and COM2

for serial ports. This means that applications cannot detect

and use the serial ports.



Workaround: To create the symbolic names, you can write an

application that calls the DefineDosDevice function and

uses the full device name of the port. Add this application to

Startnet.cmd so that it runs as part of the Windows PE boot

process. When the application is finished, applications

can detect the serial ports by their symbolic names.



The full device name of COM1 when using the ACPI

HAL is:



  \\?\ACPI#PNP0501#1#{4D36E978-E325-11CE-BFC1-08002BE10318}



To identify the full device names for serial ports on other HALs,

use the QueryDosDevice function to search for the string "PNP0501".



To use serial ports in custom applications, either refer to the

ports by their full device names or use DefineDosDevice to create

the symbolic names as in this example:



  #define COM_PORT_DEV_NAME(n) \

    TEXT("\\\\?\\ACPI#PNP0501#") TEXT(#n) TEXT("#{4D36E978-E325

     -11CE-BFC1-08002BE10318}")



  #define COM_PORT_NAME(n) \

    TEXT("COM") TEXT(#n)



  DefineDosDevice( 0, COM_PORT_NAME(1), COM_PORT_DEV_NAME(1) );



*/



#include <windows.h>



#define COM_PORT_DEV_NAME(n)  TEXT("\\\\?\\ACPI#PNP0501#") TEXT(#n) TEXT("#{4D36E978-E325-11CE-BFC1-08002BE10318}")

#define COM_PORT_NAME(n)      TEXT("COM") TEXT(#n)



void main()

{

    DefineDosDevice(0, COM_PORT_NAME(1), COM_PORT_DEV_NAME(1));

}

把msports.dll也加上即可安装。

我装好了：

txtsetup.sif不用改。
只要复制SERIALUI.DLL、MSPORTS.DLL就可以安装了。

甚麼特別的程式要用 com 呢?

批次安裝可用911的做法.  利用 hwpnp.exe
HWPNP.EXE -all +ACPI\PNP0501\1 +ACPI\PNP0501\2 /u /p
501 是 com
401 是 lpt

谢谢各位了
已经成功安装

如何在PE下使用COM老式鼠标？

jxdcjj

我下载了HWPNP.EXE
运行后还是没有看到端口，PE环境是通用的，能给个详细的方法吗？
