[ros-kernel] Attempt at fixing gets

[Jason F. <ja...@gl...>]

Technically gets is not at fault... the problem is downstream as =
everyone knows. I have what appears to me to be a fix. Before I submit =
it, please would those that know console code better than I do make sure =
I'm not just fixing a symptom. Thanks!

FILE: reactos\lib\msvcrt\stdio\stdhnd.c:

 // stdin
{
 NULL, 0, NULL,
  _IOREAD | _IOLBF | _IONBF,
  0, 0,0, NULL
},

NOTE: For the definition of stdin I added the _IONBF flag, which seems =
to be required to make pressing Enter work right.

FILE: reactos\lib\kernel32\file\rw.c: (At about line 103, function =
ReadFile)

Add two new variables:
   DWORD oldStdinMode;
   WINBOOL consoleResult;

Then replace the first few lines of code with:

   if (IsConsoleHandle(hFile))
     {
 GetConsoleMode(hFile, &oldStdinMode);
 SetConsoleMode(hFile, ENABLE_ECHO_INPUT | ENABLE_PROCESSED_INPUT);

 consoleResult =3D ReadConsoleA(hFile,
       lpBuffer,
       nNumberOfBytesToRead,
       lpNumberOfBytesRead,
       NULL);

 SetConsoleMode(hFile, oldStdinMode);
 return consoleResult;
     }

NOTE: What it does is set the stdin to echo all input (that was missing =
if it's not specified). Also save and load the previous stdin settings, =
otherwise when you go back to the command line it's broken.

Comments please

Thanks!
