You're rigth. I'll try to do it later. BTW this is not a daemon (i'm
thinking on put it as option).

int tputs(const char *str, int affcnt, int (*putc)(int));
Could you explain me better how to do it ?
1. third argument [int (*putc)(int)] of tputs() only send one argument
to those argument! How can I also send client's descriptor ?
2.
int fputc(int c, FILE *stream);
Second argument of fputc() is a (FILE *) and the client's
descriptor it's an integer (int). Maybe try write or send !?

That's rigth! :-) It was my mistake. ;)

I had changed from "vt100" to (char*)0 !! It's better, rigth !?

I don't know. My project it's for an Introduction to Networking ...
I need use socket(), accept(), listen(), etc ...

What do you mean by handle connections using inetd !? I'm using
telnet/tcp/23 . I need to use the protocol's stack TCP/IP!
The same question about in.telnetd !
