The following program is based on the following newsgroup post:
http://forum.dlang.org/post/[email protected]
The program prints character codes in hex until it sees Ctrl-D:
import std.stdio : writef, writeln;
import std.c.stdio;
import std.c.linux.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();
}

Please don't say that. :) Thank you very much for communicating in English.
