Hi Jaben, Thanks for your reply.
Please check the below test report. 1) Launch the application that displays the Key Uni code and Scan code using Conplitter readKey function. The application comes out when the "Enter" Key is pressed 2) Pressed "a", "b", "c","d","Enter Key"(many times) 3) We could see the application displays some of the key uni code and scan code that pressed 4) Once application detects the Enter Key , it comes back to Shell command prompt. In the shell command prompt we are able to see what ever key missed by the application I think this would confirm that Shell does the readkey when the application is active. Is it not?

You can also run the "edit" command. If that application can catch the keystrokes, instead of the shell, then I think it could confirm that the shell is not hindering the capture. -Jaben -----Original Message----- From: Ramesh R.

Can we send our application source and is it possible to check it on your side? Or is there any other way that we can prove, Shell is not reading the key when the application is active?.

The thread from the shell is in your application at that time. I would guess that the ReadKey gets called after your application ends and then it handles the information from the key that was pressed during the application's time. -Jaben -----Original Message----- From: Ramesh R.

C file having function FileInterfaceStdInRead, which is reading Key data with wait for event and even after I am my in application, FileInterfaceStdInRead function 's ReadKey is working .I checked this by printing messages with each call to ReadKey of FileInterfaceStdInRead function. So while coming Back to shell we can see this message with key pressed. By this we can say when application is running, shell's ReadKey is also responding. Could you please provide your comments on this?

Unless a CTRL-C or CTRL-S comes via the events, there is nothing happening inside the shell. Your application is started around line 1607 in shell.c -Jaben -----Original Message----- From: Ramesh R.

We are just launching the application from shell. Not doing any other things. Could you please tell me where( file name) are we stopping Shell ReadKey Function while launching the Application? Or How are you saying " The shell does not read from console in while your application is running" Thanks, Ramesh -----Original Message----- From: Carsey, Jaben [mailto:jaben.car...@intel.com] Sent: Monday, October 07, 2013 10:16 PM To: edk2-devel@lists.sourceforge.net Subject: Re: [edk2] ConsoleIn behavior with Shell Ramesh, I cannot think of why that would happen. Which revision of the shell are you using? Is there anything odd about the launch of the application? For example redirecting input to/from a file or anything like that? -Jaben -----Original Message----- From: Ramesh R.

We are getting the Key using System table ConIn like how Internal EDIT command gets the Keystroke. To reproduce the issue on your side, 1) Boot to Shell Prompt. 2) Launch UEFI OS installation 3) It would ask "Press any key to proceed installation" . This time press any key, sometime you would see it won't proceed with installation and once it comes back from Shell prompt you would see the same Key gets printed .

It will read any characters left in the buffer when your application closes. The internal Edit command gets keystrokes via: Status = gST->ConIn->ReadKeyStroke (gST->ConIn, &Key); How are you reading the keystrokes? Which SimpleTextIn protocol instance are you using? -Jaben -----Original Message----- From: Ramesh R. [mailto:rame...@ami.com] Sent: Monday, October 07, 2013 8:25 AM To: edk2-devel@lists.sourceforge.net Subject: [edk2] ConsoleIn behavior with Shell Hi, We have shell Application that would read the ConsoleIn ( Keyboard) device data on every 500ms. Most of the time application is not receiving the data by using SimpletextEx ReadKey Protocol, Looks like Shell gets the data before application does. The reason why we are saying Shell gets the data because we are able to see all the ConsoleIn device data printed once we come back to Shell Prompt. Could you please provide your comments on this behavior? Thanks, Ramesh The information contained in this message may be confidential and proprietary to American Megatrends, Inc.
