本文介绍如何在Vmware环境中通过管道来接收串口数据，以方便查看调试信息。提供了一个C语言程序示例，该程序连接到名为 '[url=file:////.//pipe/PipeWinCEDebugMsg]//.//pipe/PipeWinCEDebugMsg[/url]' 的管道，并将接收到的数据记录到'pipe.log'文件中。

Vmware上支持串口，可以使用物理串口、文件、管道三种方式。如果想查看调试串口信息，使用管道自然是十分方便的。我写了一个接收管道数据的程序，这样可以看到调试串口打印的信息，管道名称是[url=file:////.//pipe/PipeWinCEDebugMsg]//.//pipe/PipeWinCEDebugMsg[/url]，代码如下：
#include <Windows.h>

int _tmain(int argc, _TCHAR* argv[])
{
HANDLE CltHandle;
TCHAR pipenamestr[50];
CHAR cBuffer[1025];
DWORD dwRealSize;
HANDLE hFileLog = CreateFile(TEXT("pipe.log"), FILE_APPEND_DATA, FILE_SHARE_READ, NULL, OPEN_ALWAYS, NULL, NULL);
CHAR cStartMsg[] =   "*****************************Start*******************************/r/n/r/n/r/n";
CHAR cEndMsg[] = "/r/n******************************End********************************/r/n/r/n/r/n";
wsprintf(pipenamestr, TEXT("////.//pipe//PipeWinCEDebugMsg"));
printf("Client Started!/r/n");
while(1)
{
  if (WaitNamedPipe(pipenamestr, NMPWAIT_WAIT_FOREVER) == FALSE)
  {
   printf("Wait Pipe Error, please Check Server Config!/r/n");
   Sleep(1000);
   continue;
  }
  CltHandle = CreateFile(pipenamestr,
   GENERIC_READ | GENERIC_WRITE,
   FILE_SHARE_READ | FILE_SHARE_WRITE,
   NULL,
   OPEN_EXISTING,
   FILE_ATTRIBUTE_ARCHIVE|FILE_FLAG_WRITE_THROUGH,
   NULL);

  if (CltHandle == INVALID_HANDLE_VALUE)
  {
   printf("Connect to Server Error！/r/n");
   Sleep(1000);
   continue;
  }
  else
  {
   printf("Pipe Connect Successfully!/r/n");
  }

  WriteFile(hFileLog, cStartMsg, sizeof(cStartMsg), &dwRealSize, NULL);
  while(ReadFile(CltHandle, cBuffer, 1024, &dwRealSize, NULL))
  {
   cBuffer[dwRealSize] = '/0';
   printf("%s", cBuffer);
   WriteFile(hFileLog, cBuffer, dwRealSize, &dwRealSize, NULL);
  }
  WriteFile(hFileLog, cEndMsg, sizeof(cEndMsg), &dwRealSize, NULL);
  CloseHandle(CltHandle);
}

CloseHandle(hFileLog);
return 0;
}
