This is because using the standard functions, i/o is buffered and no
doubt that your terminal in canonical mode instead of cbreak mode.

As for a better solution, why not simply make a termcap (or terminfo)
defintion for a terminal type 'regis'.  Then, all you need is something
as simple as:

	if ( strcmp(getenv("TERM"),"regis") == 0 ) {
		/* then I have this terminal type */
		}
	else
		{
		/* whatever */
		}

If you want some more specific help, then send me email.
