How to supply console input ( yes / no ) as part of batch file on Windows.

I am writing a simple batch file (remove.bat) to remove a directory and all its subdirectories. The file contains the following command-

rmdir /S modules

where modules is the name of the non-empty directory.

I get the following message -

C:\...\bin>rmdir /S modules
modules, Are you sure (Y/N)?

How can I supply through the batch file the console input "Y" to the Y/N question above? Is there a command that can do this?
