I've just found the following code among my collection of D snippets, 
which uses a different method and supports Ctrl-D:

import std.stdio : writef, writeln;
import core.stdc.stdio;
import core.sys.posix.termios;

/* The declaration of cfmakeraw, which is missing from standard D 
modules. */
extern(C) void cfmakeraw(termios *termios_p);

void main()
{
     /* Saving the existing state of tty. */
     termios oldState;
     tcgetattr(1, &oldState);

     /* Ensuring that it will be restored upon exit. */
     scope (exit) tcsetattr(1, TCSADRAIN, &oldState);

     /* Make a new state and set it to raw mode. */
     termios  newState;
     tcgetattr(1, &newState);
     cfmakeraw(&newState);

     /* Use the new state in this terminal. */
     tcsetattr(1, TCSADRAIN, &newState);

     /*
      * We are ready to read characters in this raw mode...
      */

     /* This is Ctrl-D, the EOF character under Linux. */
     enum endOfFile = '\4';

     for (char c; c != endOfFile; ) {
         c = cast(char)fgetc(stdin);
         writef("%02x ", c);
     }

     writeln();
}
