//
// Routine Description:
//
//    This function displays the prompt string on the debugging console and
//    then reads a line of text from the debugging console.  The line read
//    is returned in the memory pointed to by the second parameter.  The
//    third parameter specifies the maximum number of characters that can
//    be stored in the response area.
//
// Arguments:
//
//    Prompt - specifies the text to display as the prompt.
//
//    Response - specifies where to store the response read from the
//       debugging console.
//
//    Prompt - specifies the maximum number of characters that can be
//       stored in the Response buffer.
//
// Return Value:
//
//    Number of characters stored in the Response buffer.  Includes the
//    terminating newline character, but not the null character after
//    that.
//
